I found another great recipe: http://nancysrecipes.wordpress.com/2008/10/06/bbq-beef-sandwiches-crockpot/

BBQ Beef Sandwiches

3 to 4 lb. beef chuck roast
1 1/2 cups ketchup
1 (1 ounce) pkg. onion soup mix
1 tbsp. chili powder
3 tbsps vinegar (I use red wine vinegar)
1 tbsp. Worcestershire sauce
2 tsps. prepared mustard
1/4 tsp. garlic powder
Kaiser rolls
Cheese slices, your choice (I use monterey jack)

Trim fat from beef and place in crockpot.

Stir together all remaining ingredients together ~ except rolls and cheese ~ and pour over meat in crockpot.

Cover and cook on LOW for 8 to 10 hours or on HIGH for 4 to 5 hours, or until fork tender.

Skim off fat. Remove meat from crockpot and shred. Return meat to sauce in crockpot.

Spoon about 1/4 cup of meat on bottom of each roll and top with cheese. Place under broiler to melt cheese if desired.

Makes 6-8 sandwiches.

The only thing is it was not done until closer to 6-7 hours on high. I’m not sure if every crockpot is the same in that regard, but in the future I’ll definitely make it an all day thing if I want to eat supper on time. Otherwise the recipe was a winner here!
