2 1/2 lb. pork roast
1 (14 oz.) bottle favorite barbecue sauce (I use 1 3/4 c. sauce)
1 tsp. brown sugar
1 tbsp. lemon juice
1 medium onion
hamburger buns

Place pork roast in slow cooker, cover and cook on high for 5 to 6 hours. Remove roast and pull meat into shredded pieces. Pour out any liquid in the pot and combine pork with the remaining ingredients in slow cooker. Cook on high for 2 hours. Serve on buns.
