Gon chau ngau ho (beef chow fun)

Method

1. 1 Marinate thinly sliced beef (across the grain) with soy sauce, cornstarch, and sesame oil for 15 minutes.
2. 2 Separate the rice noodles into individual strands and drain them thoroughly so they don't break apart when stir-frying.
3. 3 Heat the pan until very hot, stir-fry the beef for 1 minute until medium rare, then transfer to a plate.
4. 4 Add the rice noodles to the pan, stir gently for 2 minutes until the noodles are slightly browned, then season with soy sauce, oyster sauce, and sugar.
5. 5 Add the beef to the pan with bean sprouts, onion, and scallions, stir-fry quickly for 1 minute, then turn off the heat and sprinkle with pepper.
