I'll go out on a limb and say that grilled tuna is the best thing going. Bar none. Better than a filet mignon, better than ribs or chicken or tenderloin or anything else.
Dredged in soy sauce and sesame oil, grilled for 5 minutes a side. Served with rice or anything going.
Yep, give me a good cut of tuna, a hot grill and some chopsticks and I'm there.
