To Cook the Noodles
Lightly blanch the noodles in some boiling water to avoid them sticking together.
Heat up the oil in a wok over medium high heat. Add the noodles, dark soy sauce and light soy sauce.
Stir fry and toss until the noodles are evenly coated with the soy sauce. Continue until the noodles are cooked. Set aside.
To Cook the Gravy
Heat up some oil in the wok and fry the garlic until golden brown.
Next add the chicken, fish cake and prawns. Fry until the prawns and chicken are cooked and pour in the chicken stock
Season the chicken stock with the light soy sauce, oyster sauce and salt to taste. Once seasoned, bring the stock up to a boil.
Prepare a cornstarch mixture by adding the cornflour to water and mixing well, making sure there are no lumps.
Pour the cornstarch mixture into the chicken stock and simmer until the gravy thickens.
Add the choy sum into the gravy and crack the eggs in as well.
Turn the heat off as soon as you crack the eggs in and stir vigorously to break up the eggs and mix them into the gravy.
Pour the gravy over the prepared noodles and serve immediately.
