Ingredients

  • 1 pound flank steak, thinly sliced
  • 5 tablespoons soy sauce
  • 1/4 cup sriracha sauce
  • 1/4 cup chopped green onion

Method

  • Place flank steak slices in a shallow dish.
  • Mix soy sauce, sriracha sauce, green onion, sugar, whole dried peppers, garlic, sesame seeds, sesame oil, ground cayenne, and black pepper together in a bowl. Pour over steak. Cover with plastic wrap and refrigerate to marinate, at least 1 hour but preferably overnight.
  • Preheat an outdoor grill for high heat, and lightly oil the grate.
