Remove the beef from the wok and set aside. Add the remaining 1 tablespoon of vegetable oil to the wok. Add the white parts of the scallions and stir-fry for about 30 seconds until fragrant.

Pour the prepared sauce into the wok and bring to a simmer. In a small bowl, mix the remaining 1 tablespoon of cornstarch with 2 tablespoons of water to create a slurry. Add the slurry to the simmering sauce, stirring constantly until the sauce thickens.

Return the cooked beef to the wok. Add the green parts of the scallions and toss everything together to coat the beef evenly with the thickened sauce. Cook for another minute until heated through.
