Pat the Ahi Tuna steaks dry with a paper towel. Set aside.
In a small bowl mix the soy sauce, sesame oil, honey, salt, pepper, and crushed red pepper.
Dip Ahi Tuna steaks in Soy Sauce mixture, then place in sealable plastic bag (or bowl).
When all Ahi Tuna steaks are dipped and placed in bag, pour the mixture in with the tuna, and seal or cover. Allow to marinate for at least 15 minutes, but 2 hours is best.
When Ahi Tuna steaks are marinated, remove from bag and retain liquid in bag. Place sesame seeds in small plate, and dip each ahi tuna steak, covering top and bottom.
Heat skillet over medium-high heat for a few minutes, and add 1 tablespoon cooking oil.
Carefully place Ahi Tuna steaks in hot oil. For 1” thick steaks, sear for approx. 1 minute on each side. For 1.5 inch steaks, it will increase to 1.5 to 2 minutes per side. Leave on heat an additional 30-60 seconds if you desire them more fully done.
When Ahi Tuna steaks are seared (they will be medium-rare inside), remove from heat and place on cutting board, and drizzle with some of the leftover marinate sauce.
Slice ahi tuna steaks in thin slices (about 1/2 inch), and lean them a little to display on plate.
Garnish with chopped Green Onion, sprinkled Sesame Seeds, and Lime wedges.
Enjoy!
