Ingredients

2 tablespoons soy sauce

2 tablespoons dry sherry

1 tablespoon sugar

2 teaspoons rice vinegar

1/2 teaspoon red-pepper flakes

1/2 teaspoon cornstarch

1 tablespoon plus 1 teaspoon vegetable oil

3/4 pound boneless New York strip steak, thinly sliced

2 red bell peppers, ribs and seeds removed, thinly sliced

2 garlic cloves, minced

1 tablespoon sesame seeds, toasted

Cooked rice, for serving

Thinly sliced scallions greens (optional), for serving

Preparation

In a small bowl, combine soy sauce, sherry, sugar, vinegar, red-pepper flakes, and cornstarch. In a large skillet, heat 1 tablespoon oil over medium-high. In 2 batches, cook meat, undisturbed, until browned on one side, about 2 minutes per batch. Transfer to a plate.

Add 1 teaspoon oil and bell peppers to skillet and cook, stirring, until peppers are crisp-tender, 2 minutes. Add garlic and cook until fragrant, 30 seconds. Whisk soy sauce mixture and add to skillet, along with steak. Cook, stirring, until sauce thickens, 1 minute. Stir in sesame seeds. To serve, spoon beef mixture over rice and top with scallion greens, if desired.
