Tuna is another familiar and popular menu choice for diners. Its meaty, firm texture has a mild taste and pairs well with almost any seasoning, especially Asian flavours. Yellowfin tuna, also known as Ahi Tuna, is widely used in fish dishes, especially sashimi. It is great for grilling and is often served seared or rare. Tuna steaks can be baked, broiled, grilled or sautéed. Low in fat and high in omega-3, tuna steaks are a great choice for the health conscious person and a great alternative to beef steaks.
