I have one that I stole from my mother. Our family enjoys it and it seems to go over well at gatherings. It involves 5 ingredients in addition to the meat.
1lb hamburger, browned and drained
1 can campbells tomato soup
1 generous squirt of ketchup
1 smallish squirt of mustard
2 or so tablespoons of brown sugar
1 or so teaspoons of worchestershire sauce.
We just go by feel on the measurements as you can tell.
