Drizzle the butter over 4-pieces of heavy-duty foil (about 18"x12"). Cut fish into 4 portions; place one portion on each piece of foil. Sprinkle all with seasoned salt and lemon-pepper. Top with vegetables & cheese . Loosely wrap foil around fish; seal top and sides. Place in a 350 degree oven for 23-25 minutes or until fish flakes easily with a fork. Carefully open foil; transfer fish & vegetables to serving plates.
