Grilled Yellowfin Tuna

Ingredients
2 pounds yellowfin tuna steaks
1/4 cup orange juice
1/4 cup soy sauce
2 tablespoons ketchup
2 tablespoons vegetable oil
2 tablespoons chopped parsley
1 tablespoon lemon juice
1 clove garlic, finely chopped
1/2 teaspoon oregano
1/2 teaspoon pepper

Directions
Thaw steaks if frozen. Cut into serving-size portions and place in a single layer in a shallow baking dish. Combine remaining ingredients. Pour sauce over steaks and refrigerate 30 minutes, turning once. Remove fish, reserving sauce for basting. Place fish in well-greased, hinged wire grills. Cook about 4 inches from moderately hot coals 5 to 6 minutes. Baste with sauce. Turn and cook for 4 to 5 minutes longer or until steak reaches 140 degrees, internally. Tuna should have a pink center.
