1-1/2 pounds ground beef
1 med onion chopped
1 can Chicken GUMBO soup
2 C chili sauce (comes in bottles and is called Chili Sauce)
1/4 C Catsup (or ketchup hehehe)
2 teaspoon Mustard
Put all ingredients in the crock pot and stir. Cook on low all day long. Serve on toasted burger buns.
NOTE:
If you decide to cook this on top of the stove, you can brown the burger before mixing all the ingredients. I did NOT do this when I put it in my crockpot. The burger was fresh, uncooked burger.
