For a healthy fish dinner, try seasoned baked cod. Heat oven to 350 F. Lightly coat 4 squares of aluminum foil with cooking spray. Place a 4-ounce cod fillet on each piece of foil. Squeeze a lemon wedge over each fillet, and sprinkle each with 1/2 teaspoon of your favorite seafood seasoning. Wrap the aluminum foil around the fish. Place in oven and bake until fish is opaque throughout when tested with knife tip, about 10 minutes.
