Pulled Pork Sandwiches

4 lbs boneless pork ribs
1 bottle barbecue sauce
1 tsp dry mustard or a tablespoon of yellow mustard
1 tsp garlic powder
3/4 C brown sugar (optional)

Pour half the bottle barbecue sauce into the bottom of the crock pot. Add all the boneless pork ribs to the crock pot. Pour the remaining barbecue sauce over the boneless pork ribs. Add the dry mustard, garlic powder, and brown sugar, if using. Stir well to cover the pork ribs with barbecue sauce. Cook on high for four hours or low for six to eight hours (depending on the thickness of the boneless pork ribs). When the pork ribs are cooked through use a fork to pull the tender pork meat apart. Serve on buns.
