Brown the beef and onion, chopped. Combine all ingredients in casserole and bake @ 350 for 1 1/2 hours. Save the bean liquids from the cans to add if they should get too dry.

This can be made the day or several days before, frozen, and then reheated with the cover on on the day that you are taking them. (I know, I'm doing just that on Tuesday <G>).
