Tracy gave me this recipe that my mom has made for years. It is great for burger cookouts or with fried chicken.
2 cans kidney beans
2 cans butter beans
2 cans pork and beans
1 pound of bacon
½ onion
¾ pound of hamburger
1 cup ketchup
½ cup brown sugar
½ cup vinegar
Rinse and drain beans. Fry bacon and crumble. Saute the onion in bacon grease and set aside in small bowl. Fry hamburger in same skillet. Mix beans, onion, bacon, and hamburger in big casserole dish with only ½ bacon grease. Mix up sauce of ketchup, brown sugar, and vinegar. Add to casserole and mix. Cook at 350 for 30-45 minutes.
