Cod a la Spetse (Greek Fish)

1 lb. frozen cod (or halibut) fillets
1/3 cup olive oil or vegetable oil
1/4 cup dry white wine or water
1/2 cup chopped fresh parsely
3 Tbs. lemon juice
1 clove garlic, minced
1/2 tsp. salt
1/4 tsp. black pepper
1 medium tomato, diced
1/2 cup soft bread crumbs

Cut the partially frozen fish into 4 even portions.
Brush 1 Tbs. of the oil in the bottom of a shallow baking dish large enough to accommodate the fish pieces in 1 layer with space in between.
Mix remaining oil with wine, parsely, lemon juice, garlic, salt and black pepper.
Sprinkle diced tomato over fish and pour on the oil-wine mixture.
Sprinkle with bread crumbs.
Bake at 350 degrees for about 40 minutes or until fish flakes when probed with a fork.
If fresh fish is used, decrease baking time to 25 minutes.
Serve with boiled whole potatoes, tossed green salad, crusty French bread
