This spinach, goat’s cheese and Prosciutto quiche makes a lovely lunch or light dinner in summer. In what is quite a classic combo, the salty goat’s cheese and ham are matched by the sweetness of the caramelised onions. You could use any savoury shortcrust pastry pastry (or buy it ready-made, of course). I used Michel Roux’s flan pastry recipe. I used skimmed milk, which keeps it quite light. If you want a richer filling for your quiche, you can add cream instead of the milk, or a use a mixture of both.
