Ah, the wonderful summer! Quiches are an important part of French cuisine and are particularly popular in the warmer months. When I stay with my in-laws in the south-west of France, I make them very regularly. The variations on quiches are endless: everyone can invent their own. Today, I'd like to share with you my ADDC-style Italian quiche - a recipe that has also been a big hit with my clients in London. Served hot or cold, with a nice salad, it's a simple and delicious lunch.
