- 1/4 cup soy sauce
- 1 tablespoon sugar
- 2 teaspoons Asian sesame oil
- 1 bunch scallions (white and pale green parts separated from greens), minced
- 1 tablespoon minced garlic
- 1 tablespoon minced peeled fresh ginger
- 3 tablespoons sesame seeds, toasted
- 1 pound flank steak, cut across the grain into very thin slices (no more than 1/8 inch thick)
- 1 tablespoon vegetable oil
- Accompaniments:
- Butter lettuce or other soft-leaf lettuce
- Thinly sliced garlic
- Packaged kimchi
- Steamed white rice
- Stir together soy sauce, sugar, sesame oil, white and pale green scallions, garlic, ginger, and 2 tablespoons sesame seeds in a bowl until sugar is dissolved. Add steak and toss to coat, then marinate 15 minutes.
- Heat vegetable oil in a 12-inch heavy skillet over high heat until just smoking, then add steak in 1 layer and saute, turning over occasionally, until browned and just cooked through, about 5 minutes total. Transfer to a platter and sprinkle with scallion greens and remaining 1 tablespoon sesame seeds, then serve with accompaniments.
