Preparation:

Cut scallops in half crosswise. Combine scallops and shrimp in a bowl; set aside. Combine sherry and next 5 ingredients; pour over seafood. Cover and marinate in refrigerator 30 minutes. Discard mushroom stems, and cut caps in half lengthwise; set aside. Remove seafood from marinade, reserving marinade. Thread 2 scallop halves, 6 shrimp, 2 green onion pieces, and 2 mushroom halves alternately onto each of 4 (12-inch) skewers. Coat grill rack with cooking spray; place rack on grill over medium-hot coals. Place kebabs on grill rack, and cook 4 minutes on each side or until shrimp and scallops are done, basting occasionally with reserved marinade.
