DO-AHEAD TIP: Marinate lamb chops overnight or for at least 4 hours (see recipe).
Prepare marinade: In a large bowl, whisk together all ingredients, except lamb chops, until fully blended.
In a large zipper-topped plastic bag, place lamb chops; pour marinade on top, seal bag and refrigerate overnight or for at least 4 hours.
Preheat outdoor or indoor grill to MEDIUM-HIGH. Remove chops from marinade (reserving marinade) and sear on grill for 4 to 6 minutes per side or until cooked through to your preference.
Heat reserved marinade in a medium skillet over medium-high heat; whisk for 1 minute then reduce heat and simmer until slightly reduced (about 5 minutes); serve over lamb chops.
