Spritz the liner of your Crock with nonstick cooking spray. Place the pork loin chops in the bottom of the slow cooker and season with salt and black pepper.
Top with the barbecue sauce. Place a layer of aluminum foil over the pork. Place the potatoes (rinsed and dried) over the foil. Cover and cook on low for 6 to 7 hours or high for 3 to 4 hours or until the potatoes are cooked through and fork tender.
Carefully remove the potatoes and foil from the slow cooker. Shred the pork with two forks. Split the potatoes open and top with pulled pork and shredded cheese.
Serve with any topping desired such as sour cream, sliced green onions, additional barbecue sauce, or cooked bacon.
