How to Build a Week of Low-Cost Plant-Based Meals

Some of the cheapest food in the store sits in plain bags and cans, and it rarely gets any attention.

Dried beans, lentils, rice, oats, pasta, potatoes, and frozen vegetables cost very little per serving, and they fill you up. Plant-based eating built on these foods can be one of the most affordable ways to feed yourself and your family. It does not need fancy ingredients or special equipment.

This guide shows you how to build a full week of low-cost plant-based dinners from one shopping list, with simple breakfasts and lunches as well. You do not need to give up animal foods completely to use it. Many people simply fill a few nights a week with these meals. I will also cover a few nutrition basics, because eating this way works best when you plan for them.

Start with the building blocks, and not the recipes

Low-cost plant-based cooking is easier when you think in building blocks. A few cheap foods can become many different meals. Beans and lentils for protein. Rice, pasta, oats, and potatoes for filling energy. Frozen and canned vegetables for color. Canned tomatoes, onions, and garlic for flavor. Tofu and peanut butter as extras. If you want help keeping your whole budget steady while you try new food habits, my budgeting habits that help you take control of your money may be a good companion.

Learn a few basic seasoning combinations, like cumin and chili powder, curry powder, or garlic and soy sauce. They turn the same beans and rice into very different dinners.

With a handful of building blocks, you can improvise for the rest of your life.

Look at the building blocks above, and circle the ones you already have in your kitchen.

Make one shopping list for the week

Here is a list sized for about three people, and you can scale it up or down. Dry and pantry: 1 pound of red lentils, 2 pounds of rice, 1 pound of pasta, a large container of rolled oats, a jar of peanut butter, and a pack of tortillas. Canned: 2 cans of chickpeas, 2 cans of white beans, 2 cans of black beans, and 1 large can of crushed tomatoes.

Fresh and frozen: one 14 ounce block of firm tofu, 3 pounds of potatoes, 2 pounds of carrots, 4 onions, a head of garlic, a bunch of greens such as spinach or kale, bananas, and a large bag of frozen stir-fry vegetables or broccoli. Flavor: curry powder, cumin, chili powder, soy sauce, salsa, salt, pepper, and cooking oil.

Prices differ by store and season, so I have left them out. Check what you already own, and use store brands where you can.

Check your pantry against the list, and circle only what you need to buy.

Keep breakfast and lunch simple

Breakfast can be oatmeal with peanut butter and sliced banana, which is cheap, filling, and easy. Make a big pot, and reheat portions. Toast with peanut butter, or leftover rice with a little soy sauce and vegetables are other quick options. For lunch, plan to eat last night’s dinner, or make a bean and rice bowl with salsa. If you like to see your week laid out clearly, these budgeting habits that help you build a stronger money plan can help you organize it.

Cook a large pot of rice on the first day, and use it all week. Keep a container of cooked beans in the fridge for quick lunches.

Simple repeats make the week easier and keep costs low.

Plan your breakfast and lunch for the week, and decide which leftovers will become lunches.

Night one: red lentil soup with carrots

Red lentils cook quickly and do not need soaking. Soften a chopped onion and a few chopped carrots in a little oil. Add garlic and a teaspoon of cumin, then about a cup of red lentils and about five cups of water. Simmer for about twenty to twenty-five minutes, until the lentils are soft and the soup is thick.

Season with salt and pepper, and add a squeeze of lemon if you have one. Serve with a scoop of rice or a slice of bread.

This soup is warm, filling, and costs very little per bowl. It also makes great leftovers for lunch.

Make a pot of red lentil soup, and save a portion for lunch the next day.

Night two: chickpea and potato curry

Soften a chopped onion and some garlic in oil, and stir in a spoonful of curry powder for a minute. Add about a pound of diced potatoes, a can of drained chickpeas, a can of crushed tomatoes, and half a cup of water. Simmer for twenty to twenty-five minutes, until the potatoes are tender.

Taste, and add salt as needed. Serve over rice. A handful of greens stirred in at the end adds color.

The curry freezes well, so you can double it and save a meal for a busy night.

Cook a big pot of rice, and make the curry, saving extra rice for later nights.

Night three: tofu and vegetable stir-fry

Press the tofu by wrapping it in a clean towel and setting something heavy on it for fifteen minutes. Cut it into cubes, and fry in a little oil until golden on a few sides. Add a bag of frozen stir-fry vegetables, and cook until hot.

Stir in a few tablespoons of soy sauce and a clove of minced garlic. Serve over rice. If you have peanut butter, you can thin a spoonful with soy sauce and water for a quick sauce.

Tofu is often one of the better protein values in the store, and it takes on whatever flavors you add.

Press and cube your tofu, and make the stir-fry with frozen vegetables and rice.

Night four: pasta with white beans and greens

Cook pasta according to the package. While it cooks, soften a few cloves of garlic in oil, and add a can of drained white beans and a big handful of greens. Cook until the greens wilt and the beans are warm.

Add a splash of the pasta cooking water to make a light sauce, and toss with the drained pasta. Season with salt, pepper, and a pinch of chili powder if you like some heat.

This is one of the fastest dinners of the week, and it is hearty and satisfying.

Make pasta with white beans and greens on your most tired night of the week.

Nights five to seven: burritos, a baked potato bar, and a leftover night

For burritos, warm a can of black beans with cumin and chili powder, mix with rice and salsa, and wrap in tortillas. For a baked potato night, bake potatoes at about 425 degrees Fahrenheit until tender, usually 45 to 60 minutes, and top with beans, broccoli, salsa, and a little oil or other toppings. The seventh night can be a leftover feast, with small portions of everything from the week. If you want to keep an eye on your numbers while you cook, these budgeting tips that help you manage your money with more confidence may help.

Put leftovers in the fridge within about two hours of cooking, and eat them within three to four days. Reheat food until it is steaming hot.

By the end of the week, you will have used most of your list, and you will have wasted very little.

Plan one burrito night, one baked potato night, and one leftover night for the end of your week.

Cover the nutrition basics, and keep your costs low

Plant-based eating can be healthy and affordable, and it helps to plan. Eat a variety of beans, lentils, tofu, whole grains, vegetables, and nuts or seeds. People who eat fully plant-based diets generally need a reliable source of vitamin B12, from fortified foods or a supplement, and it is wise to talk with a doctor or a registered dietitian, especially if you are pregnant, feeding children, or managing a health condition. For more ways to keep your money plan steady, my personal finance tips for building better money habits may be useful.

To keep costs low, buy dried beans or lentils in bulk when you can, use frozen vegetables, choose store brands, and cook a few big batches. Shop for what is in season, and use up what you buy.

You can start with just two or three plant-based dinners a week, and add more as it feels comfortable.

Write down the nutrition questions you have, and bring them to your next healthcare visit.
