I like beans and make a lot of items using dry beans to start with, and I have a lot of time on my hands so I go with slow cooked beans in my slow cooker as the standard. This recipe can be tailored at will with what you have on hand or what you want to use. This recipe is what I make but it also changes each time.
Variants: Use any of the following, chopped onion, tomato paste, chopped chilies, ham, bacon, or even chicken, use chicken stock instead of water, you get the idea, tailor this at will.
