Our favorite BBQ Pulled Pork Sandwich recipe

I got this recipe from the Rival Crock Pot Slow Cooker Recipes for All Occasions cookbook and our family loves it!

Ingredients:
1 Pork shoulder roast (about 2 1/2 lbs--we use a bigger one, about 3-4 lbs so we can freeze for later)
1 bottle (14 oz.) BBQ sauce
1 tbsp fresh lemon juice
1 tsp brown sugar
1 medium onion, chopped
8 hamburger buns or rolls (we use hoagie rolls)

Directions:
1. Put roast in crock pot, cover and cook on low 10-12 hours or high for 5-6 hours.

2. Remove pork; shred meat with 2 forks.  Discard any liquid in slow cooker.  Return pork to cooker, add BBQ sauce, lemon juice, brown sugar and onion.  Cover; cook on Low for 2 hours or high for 1 hour.

3. Serve on buns/rolls
