take a bunch of dry beans put them in a pot with water before sleep, wake up boil those suckas. also boil a bunch of potatoes and eggs.
now you got a bunch of potatoes and beans and egs.
beans can be converted into a chili toping for a potato with onion powder, garlic, cayenne pepper, cumin, and a squirt of tomato ketchup. I do it one portion at a time (season to taste, add other stuff if you like. very versatile)
The beans can be frozen in portion sizes then defrosted and heated up as needed (it always better to make a lot of beans at once) or stored in the fridge.
canned beans are convenient, but generally a scam.
takes some simple prep, but pretty quick once you have the beans and potatoes in your fridge. egg can be a quick snack.
you can also do rice to mix with beans. also very tasty and versatile.
