The meal I eat most often is pasta with cheese and peas. I throw in frozen peas with the pasta while it's cooking, then drain the pasta and peas and mix them with shredded cheddar cheese (the cheese melts with the heat of the pasta). It's one less pot to wash than making separate tomato sauce. (Sometimes I use butter and a bit of parmesan cheese instead of the cheddar.) Other things I eat that are easy to make: Poached eggs on toast (sometimes with a slice of cheese on top; the heat of the cooked egg melts it somewhat). Canned cannelini beans: I dump them into a colander to rinse them, then put them in a bowl and dress them with oil, red wine vinegar, and salt (no cooking). Sauteed frozen veggies (many people have mentioned frozen veggies, which are great, since washing and cutting fresh veggies is a major task). I usually do okra and peas. You have to stay at the stove to stir them a bit, but it only takes about 5 minutes. If you have the energy to tend to the stove a bit longer, tofu with frozen vegetables is not too bad to make (I usually get a stir-fry mix, so I can just throw it in). When I can't manage the stove, pots, and dishes, I make a quesadilla in the toaster oven: just put some chunks of cheddar cheese on two tortillas and toast them. Then stick them together when you take them out.It doesn't even dirty the plate. (A melted cheese sandwich is also an obvious choice, and I find it a satisfying meal. If I'm still hungry I just make another one.) If I have a bit more energy, I might make a soup by just sauteeing some onions, adding a small can of tomato sauce, then water and frozen veggies and canned beans. (Having to tend to the onions as they're sauteeing, plus having to cut them up beforehand, can be a bit of a task for us...). I also add chopped garlic and some cumin. The advantage is you can make a lot, and it's not bad even cold. I also eat nuts, as others have mentioned. Walnuts and peanuts are not as hard to chew. And I eat crackers a lot, like wheat thins. I'm a vegetarian so none of these suggestions include meat.
