Fresh or frozen tuna steaks have light-to-dark pink flesh. As the tuna cooks, the flesh lightens to a pale cream color. Albacore tuna, primarily used for canned tuna, is the only tuna that can be called white.
Sauce:
1/3 cup sliced ripe olives
1 T. pimiento-stuffed green olives
1 T. capers
2 T. olive oil
1 T. lemon juice
1 tsp chopped fresh parsley

In small bowl, combine basil, 2 tsp olive oil and 1 garlic clove; mix well. Rub on both sides of tuna steaks. Set aside.

When ready to grill, place tuna on gas grill over medium heat or on charcoal grill 4 to 6 inches from medium coals. Cook 8-12 minutes or until fish flakes easily. Turning once. Serve sauce over tuna. Sprinkle with parsley.
