“Meatless” covers dinners with eggs and dairy as well as fully plant-based meals. If you need a vegan meal, check the bread, sauce and toppings; cheese, yogurt and eggs do not fit. If you avoid particular foods because of allergies, read packaged-food labels. There is no one portion that guarantees fullness for everyone.
These two dinners begin with different staples. The potato plate is useful when you have a couple of potatoes and canned beans but do not want a pot of pasta. The lentil sauce makes sense when cooked lentils are already in the fridge or freezer. Look at what is actually on hand before shopping for either one. Buying several extra toppings to make a supposedly cheap dinner can cost more than choosing a simpler version that uses the vegetables and seasonings you already own.
Bean-topped baked potatoes
For two generous plates, bake or microwave two medium potatoes until a fork reaches the center easily. Warm one drained 15-ounce can of beans with half a 14-ounce can of tomatoes and a little cumin or chili powder. Spoon the mixture over the potatoes and add a cup of shredded cabbage for crunch. This version is vegan if the seasoning and any topping are suitable; cheese or yogurt can be offered separately to people who eat dairy. Increase the potato or bean amount if these plates would be too small for your household.
Start the potatoes before opening the cans. If using the oven, follow the size and appliance timing that works for your potatoes; if using a microwave, pierce and cook them according to its directions, turning when needed. While they cook, warm the drained beans and tomatoes in a small pan. A splash of water can loosen a mixture that becomes too thick. Taste before adding salt, especially if the canned ingredients are already seasoned. Cut each potato open only when it is tender and hot through the center, then divide the bean mixture and cabbage between the plates.
Keep optional dairy toppings on the table, not stirred into the shared bean pan. That lets a diner make a plant-based plate without you preparing two separate dinners. If cabbage is unavailable, use another vegetable that can be served safely with the meal; avoid promising that any swap has the same cost or nutrition. The leftover half-can of tomatoes needs a clean container and refrigeration, so plan where it will go before you open it.
Lentil tomato pasta
For two or three plates, cook eight ounces of dry pasta by its package. Simmer one cup of already cooked lentils with a 14-ounce can of tomatoes and chopped onion until the sauce thickens; stir in a handful of frozen spinach until hot. Toss with the pasta and save a portion of sauce for another meal if the batch allows. Dry lentils need to be cooked first by their package; they will not become tender during a few minutes of sauce simmering. This is plant-based if the pasta and toppings contain no animal ingredients. Scale the pasta and sauce together if your household needs more food.
Put the pasta water on first. While it heats, chop the onion and warm it in a pan, then add tomatoes and the cooked lentils. Let the sauce thicken while the pasta cooks, stirring so the lentils do not stick to the bottom. Add the frozen spinach near the end and heat it thoroughly. Save a little pasta cooking water if the sauce needs loosening when you toss it with the noodles. If you have only dry lentils, cook them in advance by their package instructions; do not count on a quick tomato simmer to do that job.
A generous sauce-to-pasta ratio may make this feel like a full dinner to one person, while another may want a side or a larger portion. Serve the pasta in bowls and let people decide before packing leftovers. If you plan to save some sauce, portion it before combining everything so the next meal is easier to reheat. The pasta can absorb sauce as it sits, which is a texture issue rather than a reason to add more food to the original batch.
Choose by what is already paid for
Potatoes and beans may be the better buy in one store; pasta and lentils may be better in another. Compare local package prices and the amount you will actually use. USDA MyPlate's budget guidance encourages planning and using affordable choices across food groups, but these examples are not a personal nutrition prescription. Add vegetables or fruit available to your household and adjust portions for appetite and health needs.
Compare the whole basket, not a headline price for one ingredient. A large bag of potatoes may be inexpensive per pound but wasteful if you cannot use the rest. A can of beans costs more per ounce than dry beans in some stores, but it also saves soaking and cooking time tonight. Check the price per usable portion where you shop, including any ingredient that would otherwise spoil. That makes the choice local and practical, without inventing a universal “cheapest dinner.”
Cooked portions belong in shallow containers and the fridge promptly. USDA gives three to four days for most refrigerated leftovers and 165°F (74°C) for reheating. A second meal only saves money if it is stored and eaten safely.
