3-4 lb. chuck roast

SAUCE:

1 1/2 c. catsup
Onion, cut up, as much as you wish
3 tbsp. vinegar
2 tsp. prepared mustard
1 tbsp. chili
1/4 tsp. garlic powder
2 tbsp. Worcestershire sauce

Heat oven to 350 degrees. Trim fat from meat. Put in roasting pan. Stir together sauce ingredients. Pour over meat. Cover. Bake 2 to 3 hours. Turn meat once or twice. It will be fork tender. Remove meat from sauce. I slice and cover with sauce and serve like other beef roast or you can shred meat, return to sauce. Put about 1/4 cup hot meat on bun. Top with cheese slice (Mozzarella or cheddar) if you like.
