For the marinade, place pork strips, fish sauce, lime juice, brown sugar, ginger, chillies and garlic in a bowl. Toss well to combine and set aside, covered, in the refrigerator to marinate for 3 hours.

For the dish, place noodles in a large, heatproof bowl. Cover with boiling water. Stand for 1 minute. Drain. Separate noodles and set aside.

Heat 1 tablespoon of oil in a large wok or frying pan over high heat. Add half the pork strips and stir fry for 2 minutes until browned and just cooked through. Remove the pork from the pan, set aside on a plate. Repeat cooking the remaining pork in 1 tablespoon of oil.

Heat the remaining tablespoon oil in the wok, add the red pepper, snow peas and celery and stir fry over high heat for 2 minutes. Add the rice noodles and mix.

In a small bowl, mix the cornflour together with a little vegetable stock to form a paste. Gradually add the remaining vegetable stock until well blended. Pour over the vegetables and noodles, heating on high until thickened.

Add the pork strips, cilantro and mint, stir for about 2 minutes or until heated through.
