Cover the noodles with freshly boiled water and leave them to stand for a minute. Drain and set aside until later.
Heat the oil in a large wok. Add the onion, carrot and red pepper and stir-fry over a high heat until starting to brown.
Add the garlic, ginger and pork, then continue to stir-fry until the pork is coloured on all sides.
Tip in the bamboo shoots, peas, spices, soy sauce, rice wine and rice wine vinegar, then add the noodles and stir thoroughly.
Leave to cook for a couple of minutes until hot.
Stir in the prawns and heat through.
Serve with a drizzle of sesame oil and sprinkled with the spring onions, green or red chilli, if using, and chopped fresh coriander.
