2 (6-8 ounce) ahi tuna steaks (3/4 of an inch thick)
2 Tbsp dark sesame oil
2 Tbsp soy sauce (or 2 teaspoons of wheat-free tamari for gluten-free option)
1 Tbsp of grated fresh ginger
1 clove garlic, minced
1 green onion (scallion) thinly sliced (a few slices reserved for garnish)
1 teaspoon lime juice
1) Mix the marinade ingredients together and coat the tuna steaks with the marinade, cover tightly, and refrigerate for at least an hour.
2) Heat a non-stick skillet over medium high to high heat. When the pan is hot, remove the tuna steaks from the marinade and sear them for a minute to a minute and a half on each side ( even a little longer if you want the tuna less rare than pictured.)
3) Remove from pan and slice into 1/4-inch thick slices. Sprinkle with a few green onion slices.
