From BBC's Chinese Food Made Easy, the best recent TV cookery show. Very simple to make, and tasty! I added a little more five-spice than the original recipe. Omit the chilli sauce if you wish, or add a little more to give it extra zing. If you don't have groundnut oil (peanut oil), use vegetable oil, NOT olive oil, which is too strong flavoured. Serves two as a main course, or four as a side dish.
