PREHEAT oven to 400°F. Mix dressing, jalapeno and ginger; set aside. Hold banana leaf with tongs and pass quickly across a stove burner on medium heat several times until banana leaf is pliable. (Do not overheat or leaf will become brittle.) Repeat with the remaining leaves. Line 13x9-inch baking pan with the softened leaves, with ends of leaves extending over sides of pan.
PLACE fish in prepared baking pan; drizzle with the dressing mixture. Top with the coconut and limes. Fold banana leaves over fish. Top with an empty glass baking dish to hold leaves in place.
BAKE 20 min. or until fish is cooked through. Serve in baking pan.
