DO-AHEAD TIP: Marinate lamb chops overnight or for at least 4 hours (see recipe).
Place lamb chops in a large zipper-topped plastic bag.
In a small bowl, whisk together remaining ingredients; pour mixture over lamb chops.
Seal the bag and refrigerate overnight or for at least 4 hours. At the time of cooking, preheat grill to MEDIUM-HIGH.
Remove lamb chops from marinade (discarding marinade and bag); grill lamb chops for 4 to 6 minutes per side or until cooked to the desired level of doneness.
