Fresh Chinese egg noodles are best in this dish, but any spaghetti-like noodle will work in a pinch. Almost any combination of meat and vegetables can be added. If desired, use leftover meat. Simply slice it and add at the very end, cooking just long enough to reheat it.
Have ready one of the following:
Stir together in a small bowl:
Cook in a large pot of boiling unsalted water just until tender:
Drain, rinse under cold running water, then drain again. Heat a wok or large skillet over medium-high heat. When hot, pour in:
Swirl the oil in the pan until shimmering but not smoking. Add the meat, shellfish, or tofu and stir-fry, cooking just until opaque or, for tofu or pork belly, lightly crisped. Add to the pan:
Stir-fry until the vegetables are softened, about 2 minutes. Pour the stock mixture down the side of the pan, stir, and cook 1 minute. Add the noodles, and toss to combine and heat through. If desired, add and cook for about 30 seconds:
Serve hot.
