Season the pork with salt and pepper and toss to mix.
Heat a little vegetable oil in a wok until smoking hot and toss in the pork with half the sesame oil, garlic, ginger and chilli. Stir-fry vigorously for a few minutes until the meat is almost done. Remove and set aside.
Add a little more vegetable oil to the wok. Add the vegetables and remaining sesame oil, garlic, ginger and chilli and stir-fry until almost done.
Return the meat to the wok, add the peanuts, soy sauce and noodles, and stir-fry for another minute.
Serve immediately.
Tip
Pork neck steaks are also excellent for stir-fries. / Replace the peanuts with cashew nuts if you like.
