Add the sauce and the flank steak to a reasuable container and marinate for 2 to 24 hours. (It is great to do this overnight to make this a quick meal the next day. Learn why marinating flank steak is so important.)
  • Heat a large pot of water until it comes to a roaring boil. Season with salt. Cook the noodles according to package instructions. Drain the noodles, drizzle with 1 teaspoon sesame oil, and cover to keep warm.
  • In a small bowl, whisk together 1/3 cup reduced sodium soy sauce, 1/4 cup brown sugar, 2 tablespoons oyster stauce, 1-2 tablespoons chile paste, and 2 teaspoons cornstarch. Set aside.
  • Heat 2 tablespoons of sesame oil in a large skilet. Add the marinated flank steak and the sauce to the skillet. Cook for 6 to 8 minutes, until cooked through. Remove from the pan and set aside.
  • Add 1 tablespoon of sesame oil to the skillet. Add the vegetables and cook until tender, about 5 to 7 minutes. Add the sauce, noodles, and beef to the skillet and stir to combine. Cook for an additional minute or two to allow the flavors to combine.
  • Serve and enjoy.
