M.B.
I freeze the cooked beans... I put 2 C of beans in a freezer bag, and add a bit of the bean liquid. That way I have some ready when I need it.
I don't add any seasonings or salt when I am cooking them... I wait until I put them in the dish to add seasonings.
I have about 15 bags of different beans in the freezer (red kidney beans, black beans, garbanzo beans, white beans, black-eyed peas) all ready to add to a meal!
