Rainbow Chard and Parmesan Tortino

A tortino is an oven-baked version of the Italian frittata, and makes a simple meal or the perfect picnic dish. This tortino has a slightly autumnal flavour with the rich earthiness of dried porcini and leafy greens; you can alter the flavourings to suit the season. A summery alternative might include strips of red pepper, diced courgette/zucchini and chopped spinach. Whatever you choose, do be generous with the ratio of filling to egg.
