* Fish steaks should be cut about 1-inch thick and weigh about 5 oz each.
Prepare Cilantro Pesto and set aside. Heat oven to 450 degrees F. Place the fish steaks in an ungreased rectangular baking dish 13 X 9 X 2-inches. Mix margarine and lemon juice. Pour the mixture over the fish. Bake, uncovered, until the fish flakes easily with a fork, about 20 to 25 minutes. Serve with Cilantro Pesto.
