How to Make It
Preheat oven to 425°F. Place pork chops in bowl of food processor, and pulse until roughly chopped. Add ground pork, salt, garlic powder, onion powder, and sugar; process until finely chopped and well combined.
Divide pork mixture into 4 equal portions. Shape each portion into oval patties, and place on a rimmed baking sheet coated with cooking spray. Using the handle of a wooden spoon lightly coated in cooking spray, press handle across each patty to make 3 to 4 indentions. Use your hands to shape the patties into “ribs”.
Brush patties with 2 tablespoons of the barbecue sauce, and bake in preheated oven 10 minutes. Brush patties again with 2 tablespoons of the barbecue sauce, and return to oven; adjust oven to broil, and broil until cooked through, about 2 minutes.
Spread remaining barbecue sauce evenly on 1 side of each roll, and add meat patty. Top with onion slices and pickles.
