Divide tuna filets into two deck-of-cards-sized shapes.

Fill a small dish with sesame seeds and coat the outside perimeter of the tuna with the sesame seeds.

Bring a medium saute pan to medium heat, and add olive oil. Then carefully place the tuna steaks down, laying them away from you to keep the spatter minimal. (Be careful, stray sesame seeds may pop like popcorn when they hit the oil.)

Cook 1-2 minutes per side. Flip just once.

When done, place on a bed of greens and tomatoes, add chopped scallions and dress with your favorite ginger-soy dressing. Optionally add crisp fried onions or wontons on top.
