Cook the noodles a little less than stated on the package instructions (until just underdone), then drain, rinse with cold water and set aside.
Heat the oil in the wok over high heat. Once hot, add the garlic, ginger and green onions and stir-fry for 30 secs before adding the stir fry vegetables. Stir fry for 2-3 minutes.
Add the sherry and allow to almost evaporate before adding any meat you are using and cooked noodles. Toss so that all of the ingredients are combined.
Turn the heat down to medium and add both of the soy sauces, oyster sauce, and pepper.
Stir-fry for a further 1-2 mins before adding the green onions, then toss to combine.
Fry the eggs to your liking and serve on top of the noodles.
