Arrange pork chops in one layer in a shallow dish. In a blender, blend the remaining ingredients. Pour the marinade over chops, coating thoroughly. Marinate, covered and chilled, overnight.
Discard the marinade and grill the chops on an oiled rack set 5-6 inches over glowing coals (or gas grill set on medium), for 7-8 minutes on each side, or until they are just cooked through.
