Cowboy Baked Beans

1 - 1/2 pounds of ground beef
1 large onion
1 can (16 oz) kidney beans, undrained
1 can (15-1/2 oz) great northern beans, rinsed and drained
1 can (15 oz) lima beans rinsed and drained
1 can (15 oz) chili beans undrained
1 can (14-1/2 oz) wax beans, drained
1 can (10-3/4 oz) tomato soup, undiluted
1 cup packed brown sugar
2 celery ribs chopped
2 teaspoons of dry ground mustard

Brown the ground beef and onion over medium heat in a large skillet. Drain and place in crock pot. Add all the remaining ingredients and stir together well. Cook on low heat for 5 - 6 hours.

These are the best baked beans I've ever tasted. I've taken them to pot luck meals and have never met anyone yet who didn't absolutely love them!
