1. Cook the noodles according to pack instructions. Heat a wok over high heat and add the oil. When the oil starts to smoke, add the garlic, ginger and chillies and stir fry for a few seconds. Add the beef slices and stir fry for 1-2 minutes, keeping the ingredients moving in the wok. As the meat starts to brown, add the rice wine.
2. Add the green pepper and stir fry for 1 minute. Add the noodles, breaking them up with a spoon, then add the soy and black bean sauce and stir everything together. Garnish with the sliced salad onion and serve.
