Mix all of the ingredients except the oil and melted butter in a bowl large enough to hold the chops.
Add the lamb chops and toss to coat in the marinade. Put the chops with the marinade in a zip lock bag and refrigerate overnight.
Preheat the grill.
Add the oil to the bag with the chops, reseal, and massage the bag between your hands to mix the oil. Remove the chops from the marinade.
Grill 5 minutes each side over medium flame or heat.
Let rest 5 minutes off the grill, then brush with the butter and grill 5 more minutes each side.
Serve with Pilau and green salad on the side.
