1 lb. hamburger (very lean) or lean venison burger
1 med. onion, diced
1 lg. tomato paste
3 cans water
1/2 c. ketchup
1 tsp. vinegar
1 1/2 tbsp. chili powder
1 tsp. salt

Do not brown hamburger. Combine all ingredients, adding water 1 can at a time. Cook slowly for 1 1/2 hours. Recipe may be doubled or tripled but don't increase vinegar. This freezes well for use later.
