1 pound ground beef
1 c chopped onion
1 c chopped green pepper
3/4 c ketchup
3/4 c barbecue sauce
6 T packed brown sugar
3 T molasses
3 T prepared mustard
1.5 t salt
1.5 t pepper
2 (16 oz) cans pork and beans
2 (16 oz) cans kidney beans, drained
1 (16 oz) can butter beans, drained
1 (16 oz) can pinto beans

Brown the ground beef. Add onions and green pepper and cook until tender. Place in slow cooker.

Add remaining ingredients to slow cooker. Cook on high for 1 hour, reduce to low and cook 2-4 hours.

I could add 30 oz of more beans and still have a favorable meat-to-bean ratio, however my slow cooker does not hold that much.
