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 a high heat. Once hot, add the garlic, ginger, and green on onions. Stir-fry for 30 secs.
Add 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 then toss to combine and serve.

Notes
The trick to the perfect noodle stir-fry is to cook the noodles until they are al dente or just slightly undercooked and then rinse them with cold water to stop the cooking process.
Noodles stir-fry better if you shake them after draining until dry as possible. They shouldn't be wet to the touch.
To keep your noodles from sticking before adding to the wok, add them back to their pot after draining and toss them with a little sesame oil or cooking oil.
Prepare your ingredients before heating the wok. When stir-frying, things move quickly. Have everything ready before you start.
Set the heat to high. Heat your wok before adding the oil. This step will help prevent food sticking to the pan.
Once the oil is added, spread it around the pan to coat well. Choose an oil with a high smoke point.
