Fry bacon in a large fry pan until brown. Add hamburger and brown. Drain off all but 3 tablespoons fat drippings. Add celery and onion. Cook until tender. Remove all to crockpot. Add remaining ingredients. Mix well but do not break up beans. Heat on low for 6 hours or high for 3 hours. If using oven: pour into deep 3-quart baking dish. Bake at 300? for 1 hour. Tip: to decrease carbs use low carb ketchup and low carb brown sugar.
