In a large skillet or medium sauce pan brown and drain the beef (optionally you a can brown with 1/4 cup each of diced onion, celery and/or green pepper but then its not a can opener recipe any more).
For faster prep time on the day of the meal the beef can be cooked in advance and frozen, then warmed in the microwave. open all the cans. drain the kidney beans, black beans and corn. combine all ingredients and simmer 5 minutes or until warmed through.
