Place pork chops in a large zipper-topped plastic bag. In a small bowl, whisk together remaining ingredients; pour mixture over pork chops.
Seal the bag and turn to coat; refrigerate overnight or for at least 4 hours. At time of cooking, preheat grill to MEDIUM-HIGH.
Remove pork chops from marinade (discarding marinade and bag) and grill for 5 to 7 minutes per side or until cooked through.
