MOM'S SLOPPY JOE'S

I come from a family of 7 kids...yup that would be a family of 9 total.
So my Mom always seemed to find or make a recipe that would feed a crowd. And this is one of those recipes.

2 lbs. Hamburger
2 med. chopped Onions
3 TBSP. Mustard
7 TBSP. Ketchup
1 Can Chicken Gumbo soup
1 Can cream of Chicken soup
2 tsp. Chili powder
salt to taste
pepper to taste

Brown together hamburger & onion. Add remaining ingredients. Put into crock pot, cook on Low for 2 hrs. Serve over Hamburger Buns.
