Combine tomato sauce, onion, parsley, Worcestershire sauce, pepper,
basil and sugar in saucepan. Cook and stir 5 minutes. Mix oil and
lemon juice; brush on fish. Grill sablefish 4 inches from coals 5
minutes. Turn fish, baste with tomato mixture and continue cooking
until sablefish flakes easily when tested with a fork. Allow 10 minutes
total cooking time per inch of thickness measured at its thickest
part. Thoroughly heat remaining tomato mixture; serve with sablefish.
Preparation Tip: For ease of handling, place sablefish on foil before
grilling.
