Calico Beans

These are my favorite baked beans. They go by different names (my roommate from college calls them cowboy beans), but the recipes are basically the same. The longer they bake in the slow cooker, the better they are :)

8 ounces bacon, about 10 to 12 slices
1 pound lean ground beef
1 cup chopped onion
1/2 cup brown sugar
1 tbsp. dry mustard
2 cans pork and beans
1 can lima beans or butter beans, drained
1 can kidney beans, drained
1/2 cup ketchup
1 tsp. salt
1 tbsp. vinegar

PREPARATION:Brown bacon, ground beef, and chopped onions. Combine drained ground beef mixture in slow cooker with remaining ingredients; cover and cook on LOW for 3 to 5 hours
