Method

1. Marinade the chicken with fish sauce, oyster sauce, and black pepper. This can be done a few hours in advance for more flavour, or just a few minutes if you're short on time.
2. Cook the noodles in a pot of boiling water until just cooked, then rinse in cold water and set aside.
3. In a hot wok or large frypan, heat some of the olive oil and sauté the marinated chicken for 5-6 minutes until golden brown and cooked through. Remove and set aside.
4. In the same pan, add the remaining olive oil and the white parts of the green onions. Cook for 1 minute until softened.
5. Add the cooked noodles, bean sprouts, the rest of the green onions, and the sautéed chicken. Toss well and season with the soy sauce.
6. Continue tossing over high heat for another 2-3 minutes until everything is well combined. Serve immediately.
