Use up leftover tomatoes in this rustic-style, savoury puff pastry tart with fresh herbs and crumbled feta cheese. It's easy but looks elegant enough to serve to dinner guests.
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.
