In a large saucepan, heat the chicken stock and bring to a boil.
Add the green onions, Bok Choy or Chinese greens, soy sauces, oyster sauce & the noodles.
Reduce the heat and cook according to noodle package instructions (just until tender). Serve hot
Cooking the noodles separate: If you are concerned that your noodles might suck up too much of the soup, just cook them separately (according to the package instructions), add them to the bowl and cover with the soup.
