This pie is a typical dish of Sorrento, Italy. Freshly sliced vegetables and cheese are mixed with beaten egg and baked to perfection inside shortcrust pastry.
Parmesan cheese is not truly vegetarian, as it contains animal rennet. To make this dish 100% vegetarian, omit the cheese or find a suitable vegetarian substitute made without animal rennet. In supermarkets look for the 'parmesan style hard cheeses' which are suitable for vegetarians.
