In a small bowl mix the sesame seeds with salt and pepper and roast the seeds for 30 seconds in a hot skillet.
Pat dry the Ahi tuna and marinate with soy sauce, sesame oil, and honey. Let sit for 10 minutes in the fridge.
Sprinkle all sides of the ahi tuna with the toasted sesames, pressing gently, and coat all sides.
Heat a skillet over medium-high heat, until very hot. Add the vegetable oil and carefully lay the tuna in the pan. Sear for 60 seconds from each side, until golden.
Place the seared Tuna on a cutting board and thinly slice using a sharp knife. Serve the seared tuna with a mixed herb salad and a dressing of your choice.
