Wash the fish fillet and pat dry with
paper towels. Place them in a shallow dish. Use a small bowl and combine
the ginger, garlic, chili, sugar, soy sauce and vinegar. Mix well and
spoon over he fish. Marinate for 15 minutes. Arrange the fish fillet on
a foil-lined grill tray and cook under a moderate heat for about 5-6
minutes, or until the fish is cooked through. During the cooking, do not
turn the fish. Serve hot with steamed white rice.
