In a small bowl, mix together barbecue sauce, olive oil, garlic powder, salt, and pepper.
Pat the pork chops dry with paper towels. Brush both sides of the pork chops with the barbecue sauce mixture.
Place the pork chops on the preheated grill. Grill for about 5-7 minutes per side, or until the internal temperature reaches 145°F (63°C) and the juices run clear. Brush with more sauce during the last few minutes of cooking.
Remove pork chops from the grill and let them rest for 5 minutes before serving.
Notes
Serve with your favorite sides like potato salad, coleslaw, or grilled vegetables.
