Mushroom and pak choi stir-fry

Method

1. Heat 1 tablespoon of the oil in a large wok or non-stick frying pan over a high heat. When hot, add half the mushrooms and stir-fry for 1-2 minutes, until turning golden and softened a little. Set aside while you stir-fry the rest in another 1 tablespoon of oil. Set aside.
2. Heat the remaining oil in the wok, add the shallot and stir-fry for 2 minutes. Add the garlic and ginger and cook for 30 seconds. Add the pak choi and a splash of water and stir-fry for 2-3 minutes, until the stems are beginning to soften.
3. Return the mushrooms to the pan, along with the vinegar, soy sauce and spring onions and stir-fry for 1 minute, until heated through. Season to taste and serve immediately with some steamed rice, if you like.
