Eating enough protein on a vegetarian diet does not have to be expensive. Lentils, dried beans, chickpeas, split peas, tofu, oats, and peanut butter are practical options that can help you add protein to everyday meals. The best choices depend on local grocery prices, serving sizes, and whether you eat eggs and dairy.
This guide covers 12 vegetarian protein sources, their approximate protein content, and simple ways to make your grocery budget go further.

What Are the Cheapest Sources of Protein for Vegetarians?
Dried lentils, beans, chickpeas, and split peas are useful starting points when shopping for affordable vegetarian protein. They can be stored in the pantry, used in different meals, and prepared in batches. Tofu, peanut butter, oats, and eggs can also fit into a budget-friendly eating plan.
However, the cheapest option depends on where you shop and how you buy it. A large package may cost more upfront but provide more servings. Compare unit prices and protein amounts rather than judging a food by its package price alone.
12 Affordable Vegetarian Protein Sources
The protein amounts below are approximate reference values, not guaranteed amounts for every product. Serving size, variety, preparation, and brand can change the final numbers. Check the package label or USDA FoodData Central when you need a precise value. [1]
1Lentils
Lentils are a versatile source of plant protein and fiber. One cup of cooked lentils provides approximately 18 grams of protein. [1]
Dried lentils are convenient because they can be stored for long periods and cooked in batches. They work well in soups, stews, curries, salads, and lentil bowls.
Budget tip: Cook a larger batch and refrigerate or freeze portions for later meals. This can reduce preparation time and help you use what you buy.
2Dried Beans
Black beans, pinto beans, kidney beans, and other varieties provide protein and fiber. One cup of cooked black beans contains approximately 15 grams of protein, although amounts vary by bean type.
Dried beans require soaking or longer cooking, depending on the variety and method. Canned beans are more convenient, but their price per serving may be higher or lower depending on the store and package size.
Budget tip: Compare dried and canned beans by the amount you can actually eat after preparation. If you choose canned beans, compare sodium levels and consider rinsing them when appropriate.
3Chickpeas
Chickpeas, also called garbanzo beans, provide approximately 14–15 grams of protein per cup when cooked. They also contain fiber and can be used in a wide range of meals.
Add chickpeas to salads, grain bowls, soups, or homemade hummus. You can also roast them for a crunchy snack.
Budget tip: Buy dried chickpeas when the price and preparation time work for you. Canned chickpeas can be a practical alternative when convenience matters more.
4Split Peas
Cooked split peas provide approximately 16 grams of protein per cup. They are commonly used in thick soups and stews and can help make a simple meal more filling.
Green and yellow split peas are shelf-stable pantry foods. They can be combined with vegetables, herbs, and grains for an easy meal.
Budget tip: Check the unit price of dry split peas and buy a quantity you can store and use before it loses quality.
5Textured Vegetable Protein (TVP)
Textured vegetable protein, or TVP, is usually made from soy and is often sold in a dried form. It can be rehydrated and added to chili, pasta sauce, tacos, soups, and other savory dishes.
TVP can be a useful plant-based option, but its protein content varies by product. Dry TVP is also more concentrated than the same food after water has been added.
Budget tip: Read the nutrition label and compare the price per prepared serving. Do not compare the protein in dry TVP directly with the protein in an equal weight of cooked food.
6Tofu
Tofu is made from soybeans and provides plant protein. Its protein content depends on firmness, water content, and brand. A three-ounce serving may provide roughly 6–10 grams, so check the product label for the tofu you buy.
Firm tofu works well in stir-fries, rice bowls, and baked dishes. Softer varieties can be used in soups, sauces, and blended recipes.
Budget tip: Compare the price per ounce and the protein per serving across different brands. Use tofu in meals with rice, vegetables, or other ingredients you already have.
7Edamame
Edamame are young soybeans, often sold frozen. One cup of cooked, shelled edamame provides approximately 18 grams of protein.
You can add edamame to salads, grain bowls, stir-fries, or noodle dishes. Frozen edamame is also convenient because you can use only the amount you need.
Budget tip: Compare plain frozen edamame with other available soy foods. Choose the option that fits your budget, cooking habits, and storage space.
8Peanut Butter
Two tablespoons of peanut butter provide approximately 7 grams of protein. Peanut butter also contains fat and calories, so it is best viewed as one part of a balanced diet rather than a protein source to rely on alone.
Spread it on whole-grain toast, stir it into oatmeal, or combine it with fruit for a snack. It can also be used in sauces for noodles and vegetables.
Budget tip: Compare the unit price of different jars and check the ingredient list. A store brand may be less expensive, but prices vary. Measure your serving if you want to track protein intake consistently.
9Oats
Half a cup of dry oats provides approximately 5 grams of protein. Oats are not as protein-dense as lentils or soy foods, but they are a versatile pantry staple that contributes protein to everyday meals.
Prepare oatmeal with milk or fortified soy milk, add peanut butter, or use oats in homemade breakfast recipes. You can also use them in veggie patties and other simple dishes.
Budget tip: Compare the price per ounce of plain rolled oats or other basic varieties. Flavored packets may cost more per serving and can contain added sugar.
10Eggs
One large egg provides approximately 6 grams of protein. Eggs are an option for lacto-ovo vegetarians, who include eggs in their diet, but they are not suitable for vegans.
Serve eggs with whole-grain toast, add them to vegetable dishes, or use them in simple breakfast meals. They can also contribute protein to lunch or dinner.
Budget tip: Compare the price per egg rather than the total carton price. Eggs are not automatically cheaper than plant-based alternatives in every store.
11Milk or Plain Greek Yogurt
Dairy foods can help vegetarians who eat milk products increase their protein intake. One cup of dairy milk provides approximately 8 grams of protein. One cup of plain nonfat Greek yogurt may provide around 20–25 grams, depending on the product. [1]
Milk can be added to oatmeal or smoothies. Greek yogurt works as a breakfast food, snack, or base for dips and sauces.
If you avoid dairy, choose an alternative that fits your needs. Unsweetened soy milk often provides more protein than many other plant-based milk alternatives, but nutrition varies by product. Check the label.
Budget tip: Compare the price per serving and protein content of plain yogurt, Greek yogurt, dairy milk, and soy milk. Choose the option you enjoy and can afford regularly.

12Sunflower Seeds
One ounce of sunflower seeds provides approximately 5–6 grams of protein. Seeds also supply fat and other nutrients, but they may not provide as much protein for the price as some beans or lentils.
Sprinkle sunflower seeds over salads, oatmeal, or grain bowls. You can also combine them with other seeds or nuts for a snack.
Budget tip: Compare the price per ounce and choose a package size you can use before the seeds lose freshness. Treat seeds as a useful addition to meals rather than your only protein source.
How to Buy Vegetarian Protein for Less
A few practical shopping habits can help you make better use of your food budget.
Compare Unit Prices
Package prices can be misleading. A larger package may cost more upfront but offer a lower price per ounce or serving. Use the unit-price label when available, and compare similar products. [4]
When comparing packaged protein foods, knowing how to read a Nutrition Facts label can help you compare serving sizes and protein amounts.
Consider Dried Beans and Lentils
Dried legumes are convenient pantry staples and can be cooked in batches. Canned varieties save preparation time, so the best choice depends on their price, your schedule, and your cooking facilities.
Use Store Brands
Compare store-brand and national-brand products instead of assuming one is always cheaper. Check the serving size, ingredients, and nutrition information as well as the price.
Make Use of Frozen Foods
Frozen edamame and other vegetables can be practical options because you can use the amount needed and keep the rest frozen. Compare package prices and serving sizes before buying.
Plan Meals Around Ingredients You Already Have
Before shopping, check your pantry and freezer. Build a short meal plan around foods you own, then buy only the missing ingredients. This can help reduce unused food and unnecessary purchases.
Store Food Properly
Keep dry legumes, oats, and seeds in suitable storage containers in a cool, dry place. Refrigerate cooked foods promptly and freeze portions you will not use soon. Safe storage helps protect food quality and reduce waste.
Easy Budget-Friendly Vegetarian Meal Combinations
You do not need a complicated recipe to combine vegetarian protein sources with everyday foods.
| Meal combination | Simple preparation |
|---|---|
| Lentils and rice | Serve cooked lentils with rice and vegetables. |
| Beans and whole-wheat tortillas | Make a bean wrap or simple bean tacos. |
| Oatmeal and peanut butter | Stir peanut butter into cooked oats and add fruit if available. |
| Tofu, rice, and frozen vegetables | Cook tofu with vegetables and serve over rice. |
| Eggs and whole-grain toast | Serve eggs with toast and a vegetable or fruit. |
| Greek yogurt and oats | Combine plain Greek yogurt with oats and fruit. |
| Chickpea salad | Mix chickpeas with chopped vegetables and a simple dressing. |
| Split pea soup | Cook split peas with vegetables, herbs, and broth. |
The protein in each meal depends on the amount and type of ingredients used. If you need to track your intake, calculate the total from the actual serving sizes and nutrition labels rather than relying on a generic meal estimate.

How to Choose the Right Protein Sources for Your Diet
The best vegetarian protein foods are those that fit your diet, budget, preferences, and daily routine.
Protein needs vary with age, body size, activity level, and health circumstances. A varied eating pattern can provide protein along with other nutrients. [2][3] If you have a medical condition that affects your diet or protein needs, ask a qualified health professional for personalized guidance.
Conclusion
Affordable vegetarian protein can come from everyday foods such as lentils, beans, chickpeas, split peas, tofu, oats, and peanut butter. Eggs and dairy provide additional choices for vegetarians who eat them.
To make your budget go further, compare unit prices, choose serving sizes carefully, and plan meals around ingredients you will use. There is no single cheapest protein source for every shopper, but a varied selection of practical foods can make vegetarian meals easier to plan and prepare.
