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 medium bowl, whisk together remaining ingredients. Pour mixture over lamb chops.
Seal bag and refrigerate overnight or for at least 4 hours. Preheat grill to MEDIUM-HIGH.
Remove lamb chops from marinade (discarding marinade and bag).
Grill for 4 to 6 minutes per side or until the desired level of doneness is achieved.
