I wish to eat cheap, healthy, and incredibly easy. Is this possible? It does not have to be tasty or original. I do not mind eating the same thing every day, as long as it gets me all the vitamins and nutrients required for health.
Pic unrelated. I want to be all those things, except don't care about fake.
Rice and beans are cheap and there's a lot of different ways you can prepare them or work them into a meal. Chicken thighs/legs are usually pretty cheap, as are whole chickens.
Don't bother buying just breasts unless you get them on sale for a decent price. Even then, try to get bone-in split breasts since they're cheaper than boneless/skinless and the bone helps them stay moist when cooking.
Definitely try to get whole chickens and roast them, then save the carcass and use it to make stock. Save some of the leftover chicken as well and use that, the stock and some vegetables to make soup.
Get whatever vegetables look good and are on sale and get some bags of cheap frozen vegetables as well.
Also if you eat bread regularly, start baking your own, it's much better quality and cheaper than buying the shitty preservative filled loaves at the supermarket.
So if I had a couple of eggs and an orange for breakfast, some rice (maybe with garlic powder to make it edible) and an apple for lunch, and some chicken and boiled frozen vegetables for dinner, would I be getting everything I need, or will I end up with scurvy or death or something?
More or less. I'd say have rice and beans together for lunch to make a complete protein, maybe some kind of vegetables mixed in with it too.
In terms of dietary health, try to eat a fair amount of lean protein, plenty of fresh fruits and vegetables, minimize processed and sugary foods and you'll be fine.
I'm a fan of lentils over beans, since dried lentils cook faster than dried beans, and dry of either are cheaper than canned.
Protip on rice & lentils: dump a half cup or cup of each into a rice maker, toss in a cup of chopped veggies (carrots, onion, celery, canned tomato, or whatever), add water, press "cook", then you can go play video games and forget about; will switch to "warm" when the water is absorbed. (Alternately use a slow cooker with timer shutoff). I usually add some salt & seasonings, maybe a splash of lemon juice or olive oil. Eat it as is, or treat it like a soup concentrate and add water to it in a bowl.
