Heat a wok over a high heat until just smoking and add ¼ cup oil.

Add the chicken and stir-fry for 3-4 minutes or until almost cooked.

Remove the chicken from the wok and reserve in a bowl.

Wipe out the wok, place it back on the heat and add the rest of the oil.

When hot, add the garlic and fry for a few seconds.

Add the egg and cook until it just starts to set, then add the noodles and stir well.

Add the soy sauces and stock, and bring to the boil.

Return the chicken to the wok and add the squid.

Cook over a very high heat for 1 minute or until the squid is cooked.

Add the mustard greens, bean sprouts, pepper and sesame oil, and cook for 1 minute, then transfer to a serving dish.

Serve with nuts and onion on the side, or sprinkled over the dish.
