Spread lamb flat on an oiled barbeque grill over a solid bed of medium-heat on a gas grill (you can hold your hand 1 to 2 inches above grill level only 4 to 5 seconds.). Close lid. Cook lamb, turning once and brushing with marinade, until a thermometer inserted in center of thickest part registers 140 degrees, about 40 minutes.
