Cornstarch: 1 teaspoon, for marinating the beef
Sesame oil: 1 teaspoon, for marinating the beef
For the Noodles:
Flat rice noodles (ho fun): 400g (about 14 oz), fresh or dried. If using dried, soak them in warm water until softened.
Bean sprouts: 1 cup, washed and drained
Scallions: 3, cut into 2-inch pieces
Garlic: 2 cloves, minced
Soy sauce: 2 tablespoons, for stir-frying
Dark soy sauce: 1 tablespoon, for color
Oyster sauce: 1 tablespoon, for flavor

Instructions
Marinate the Beef:
In a bowl, combine the thinly sliced beef with soy sauce, cornstarch, and sesame oil. Mix well and let it marinate for at least 15 minutes.
Prepare the Noodles:
If using dried rice noodles, soak them in warm water until they are soft, then drain. If using fresh noodles, separate them gently with your hands. Set aside.
Cook the Beef:
Heat 1 tablespoon of vegetable oil in a wok or large frying pan over high heat. Add the marinated beef slices and stir-fry until they are just cooked through. Remove the beef from the wok and set aside.
Stir-Fry the Noodles:
In the same wok, add another tablespoon of vegetable oil. Add the minced garlic and scallions, stir-frying for a few seconds until fragrant.
Add the rice noodles to the wok, tossing and stirring to prevent them from sticking. If the noodles start to stick, a splash of water can help loosen them.
Season the Dish:
Add the soy sauce, dark soy sauce, and oyster sauce to the noodles. Continue to stir and toss the noodles until they are evenly coated with the sauce.
Combine Ingredients:
Return the cooked beef to the wok, along with the bean sprouts. Toss everything together for another 1-2 minutes, ensuring the ingredients are well mixed and heated through.
Finish and Serve:
Drizzle a dash of sesame oil over the dish and give it one final stir. Serve hot, garnished with additional scallions if desired.
