Super simple, very quick, and so so good.
2 albacore tuna steaks, frozen
1 tsp olive oil
Heat olive oil in a cast iron skillet over med-high heat.
Sprinkle seseame seeds in a small plate. Pour a thin layer of soy sauce in small plate. Dip each side of one tuna steak in soy sauce, then in the seeds to coat. Place in skillet, then repeat with second steak.
Cooking time will depend on the thickness of the steaks. These were about 1 1/2 inches thick and cooked for 3 minutes on the first side and 2 minutes on the second. Don’t overcook it. Tuna steak can be cooked like beef steak – nice and rare if you want.
