Prepare the grill to high. Rub the rack of lamb with olive oil; season well with salt and pepper. (To protect the exposed bones from burning, wrap them in aluminum foil before grilling). Grill to the desired degree of doneness, turning once, about 10 minutes for medium-rare. Cut chops between ribs, place a dollop of pesto on each and serve.
