This is my favorite.....makes a lot and freezes well. Sloppy Joes - 4 lbs. hamburger, 1 cup onion, chopped, 14 oz. bottle catsup, 1 cup water, 2 T. brown sugar, 1 T. worcestershire, 1 T. salt, 2 tsp. vinegar, 1 tsp. mustard. Brown hamburger and onion, drain, add remaining ingredients, simmer and spoon onto hamburger buns. Also good on noodles, rice or baked potatoes.
