Meanwhile, heat grill. When ready to grill, remove salmon from marinade; reserve marinade. Place salmon, skin side down, on gas grill over medium-low heat or on charcoal grill 4 to 6 inches from medium-low coals. Sprinkle with pepper; cover grill. Cook 12 to 15 minutes or until fish flakes easily with fork, brushing once or twice with reserved marinade. Discard any remaining marinade.
