When the spaghetti squash is almost ready. Preheat a large skillet
to medium-high heat. Pour the sesame seeds on a plate. Then salt and pepper the ahi steaks on both sides and press into the sesame seeds to coat. Add 1 teaspoon sesame oil to the skillet. Once hot, add the ahi steaks and sear for no more than 2 minutes per side. (I do mine for 90 seconds per side.) Allow the ahi to rest.
