Just did my first yellow fin tuna steaks (from sam's) on egg-marinated 30 minutes then flipped for another 30 minutes in 1 tbsp sesame oil, 4 tbsp. soy sauce, 1 Tabasco soy sauce, and a generous dusting of slap ya mama Cajun seasoning on both sides. Cooked for 2 minutes each side at 400 and they were perfect medium. Basted heavily every 1 minute. One of the best tuna steaks I've ever eaten. Just wanted to share.
