Prepare the noodles as needed, then rinse the noodles with cold water. Drain the noodles and shake the strainer a few times to get the noodles as dry as possible. Toss the noodles with a little vegetable or peanut oil: Return the noodles to the pan you used to cook them and toss them with a little oil. This prevents them from sticking and forming a big mass in the wok. Cut the noodles.
Heat the wok and add peanut oil. Stir-fry garlic.
Add meat or vegetable ingredients: Start with stir-frying the meat. Sear for 1 minute without stirring, then stir-fry another minute to work in the aromatics. Add the vegetables. Stir-fry another minute or so until everything nearly cooked, another 1 to 2 minutes.
Add the noodles: Swirl another tablespoon of oil around the hot wok. Add the noodles and mix in with ingredients.
Add the stir-fry sauce: Season the stir-fry with the salt, and swirl in any liquid sauce ingredients, like soy sauce or chicken broth. Stir and toss the noodles and other stir-fry ingredients to coat evenly.
Stir-fry one more minute: Once the sauce has been added, stir and toss the stir-fry just another minute or so, until the noodles are warmed and any meat you’re stir-frying is cooked all the way through.
