PREHEAT broiler. Place fish on rack of broiler pan. Spread fish evenly with dressing; top with cheese.
BROIL, 5 to 6 inches from heat source, 6 to 8 min. or until fish is golden brown and cooked through, depending on thickness of fish. (If broiler does not allow you to position fish 5 to 6 inches from heat source, follow Baking Directions below.)
MEANWHILE, prepare stuffing mix as directed on package, using only 1/2 cup water and 2 Tbsp. margarine. Cook green beans. Sprinkle fish with paprika (for colour); serve with stuffing, green beans, lemon wedges and rolls.
