I really like most tinned beans, except lima beans. Definintely not a fan of lima beans. Canned tomatoes are good too, nice with a sprinkle of salt and pepper. I saw canned potatoes the other day, and unless I was stocking a bomb shelter I don't think I'll be trying those any time soon.
I have a recipe I "invented" when I was rilly poor. I don't know if it would qualify as stew or chili, but it hits the spot when you're hungry and I think it's pretty healthy. :)
Dump one can of each of the following into a large pot:
black beans
kidney beans
pinto beans
chickpeas
corn
crushed tomatoes (one large or two medium)
lentils
Add 1 tablespoon chili powder, 1 tablespoon ground flaxseed, 1 teaspoons of each: dried oregano, dried thyme, cayenne, paprika, freshly ground black pepper, mustard powder, and garlic powder (or fresh), one or two bay leaves, 1/2 cup beef stock (if you like a bit of meat taste), and two cooled and cubed baked potatoes. You can salt if you like, but I have never added salt. This makes a lot of stew/chili, and it freezes well and goes a long way.
