In a blender, combine all marinade ingredients. Blend well.
To a large zip-top bag, add lamb loin chops and marinade. Mix to make sure chops are covered with marinade. Seal and refrigerate to marinate for 5 hours, up to 24 hours.
Preheat grill to medium-high grill (450°F). Remove chops from the bag and brush off excess marinade.
Place lamb loin chops on the grill (or grilling pan) and grill until lamb loin chops reach an internal temperature of 140°F, about 15-20 minutes, turning every 2-3 minutes for even cooking and nice grill marks.
Place lamb on a platter and rest for 5 minutes. Serve and garnish with a slice of lemon.
