Use dried, not canned beans.
Slimy beans from a can are not good. That's why you should buy a bag of dried beans – invest a little time and cook them in a slow cooker. "Like rice, beans just need flavors added to the cooking process," says Kamio. Soak a pound of black or pinto beans overnight, then put them in a crockpot. Add six cups of chicken broth, a few cloves of garlic, a few slices of uncooked bacon, and whatever else you think will work. Set the crockpot on low, and they'll be done in eight hours. It'll render a lot of beans, so freeze what you don't immediately eat.
