Another delicious side dish from Signe Johansen.If feeding two or three people, use just one or two vegetables, ideally including the sweet potato, to ensure the right balance of flavours. Keep any leftover pomegranate seeds for garnishing a pudding, or a salad of leftovers the next day. The yoghurt dressing keeps for a few days in the fridge and makes an excellent dip with crispbread or toasted pitta.
