Step 1

Cook the rice in plenty of lightly salted boiling water – it will take about 12 minutes.

Step 2

Meanwhile, heat the oil in a wok or large frying pan. Add the pork and stir-fry briskly for 3-4 minutes. Tip in the spring onions, broccoli and celery and stir-fry over a high heat for 4 more minutes, then add the pak or bok choi for a minute or so until the leaves have wilted. Toss in the coriander and lime zest, squeeze in a little lime juice and add the chilli slices if you are using them. Season with salt and pepper. Heap on to warmed plates and serve with the drained rice – and sweet chilli sauce, if you like.
