Bernice Morris, from Marshfield, Missouri, pairs meatballs with sweet baked beans to create this quick-and-easy dish. "I usually serve it with a tossed green salad and dinner rolls to make a complete meal," she notes.
Combine bread crumbs, milk, salt and pepper. Crumble beef over mixture and mix well. Shape into 1-1/2-in. balls.
In a large skillet, cook meatballs and onion until meatballs are browned; drain. Add beans, ketchup, brown sugar and mustard. Bring to a boil. Reduce heat; cover and simmer for 20-25 minutes or until meatballs are no longer pink.
