A sheet of ready-made puff pastry becomes the perfect crisp, buttery base for sweet heritage tomatoes, creamy mozzarella, salty Kalamata olives and thinly sliced red onion. Add plenty of fresh thyme, a drizzle of good olive oil and a little seasoning, and you have one of those wonderfully simple tarts that looks far more impressive than the effort involved would suggest.

Serve warm, while the cheddar is still gloriously gooey and the tomatoes are soft and sweet. Perfect for a snoozy morning, lazy lunch, a quick supper or one of those occasions when you open the fridge, find a few odds and ends, and accidentally make something rather wonderful.
