Ingredients

4 tablespoons balsamic vinegar

2 green onions (white and light-green part), finely chopped

2 tablespoons coarsely grated ginger

1 1/2 pounds thick tuna steak

4 tablespoons sesame seeds

1 tablespoon oil

Preparation

  1. Mix vinegar and 2 tablespoons water with green onion and ginger in a bowl. Place tuna in mixture, and marinate about an hour. 2. To cook, remove tuna from marinade; set marinade aside. Press sesame seeds into both sides of tuna. Heat nonstick pan to medium, and add oil. Quickly sear tuna on both sides, just a couple of minutes – seeds brown quickly. Remove tuna from pan, pour in reserved marinade, and bring to a boil. Pour over tuna, and serve.
