In a medium bowl stir together ketchup, honey, soy sauce and garlic. Set aside.
Lightly season the pork chops on both sides with salt and pepper. Brush each chop with the sauce to coat.
Grease the grill grates of an outdoor grill and heat the grill to medium-high heat. Place pork chops onto the grill, and cook (while basting with the sauce often) for about 5 minutes on each side or until the meat is cooked through (the internal temperature has reached 145 degrees).
