In a small bowl combine soy sauce, sesame oil, everything but the bagel seasoning, salt, pepper, lemon juice, and hot honey. Whisk to combine.
In a shallow dish place your tuna steaks and pour marinade over them. Cover and let sit in the refridgerator for 3-6 hours. The longer the better!
Take out your tuna and over high heat get 3 tablesoons of coconut oil screaming hot in a cast iron pan. I use a dutch oven because the sides are tall and there is less splatter.
When the pan is very hot, lay one tuna steak down in the oil. Cook for 45 seconds -1 Minute depending on the level of rareness you like.
Flip to the other side and cook for an additional 45 seconds to 1 minute.
Remove from pan and lay on a cutting board to rest for 5 minutes. Repeat with 2nd tuna steak.
With a serrated knife, cut slices against the grain of the tuna.
Top with sesame seeds and sliced avocado!

Make extra marinade as a dipping sauce - This sesame-soy-honey marinade is so good, I’d honestly eat it by the spoonful. Make a little extra to serve as a dipping sauce, especially if you’re serving the seared ahi with white rice.

Use a large cast iron dutch oven to cook this so it doesn't splatter oil everywhere. Less clean up!

You must use coconut oil. It has a high smoke point which means it won't burn before getting hot enough to sear your tuna.

If you have leftover tuna, serve it up as an Ahi Tuna Salad or in some delicious Ahi Tuna Tacos
