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!
