Sprinkle fillets with 3/4 teaspoon salt and 1/4 teaspoon pepper. Place each fillet on 1 side of a piece of heavy-duty foil (about 18x12-in. rectangle). Top each fillet with peas, chives and butter. Drizzle with wine; sprinkle with the remaining salt and pepper. Fold foil around fillets and peas, sealing tightly.
Grill, covered, over medium heat 10-15 minutes or until fish flakes easily with a fork. Open foil carefully to allow steam to escape. Spoon juices over fish and peas. If desired, top with additional minced chives. Serve with rice.
