1 onion, chopped fine
1 tsp. salt
1 tsp. chili powder
1/4 tsp. pepper
2 tbsp. vinegar
2 tbsp. Worcestershire sauce
3/4 c. catsup
3/4 c. water
1 tsp. brown sugar
Cooked roast beef

Mix above 9 ingredients and simmer 45 minutes. Stir often. This makes the sauce. Tear your roast beef apart, using lean meat in thin strips. Mix with sauce and simmer 1/2 to 1 hour. May make the day before. The longer meat and sauce are together the better the taste.
