3. In a large skillet, heat the oil over medium heat. Carefully place the tomatoes in the skillet, cut sides down, and sear for about 2 minutes, or until they begin to caramelise. Pour the balsamic vinegar over the tomatoes and let it reduce over medium-low heat for 5 to 10 minutes, ensuring that it thickens slightly without moving the tomatoes.
4. Transfer the tomatoes to an 11-inch (28 cm) tart pan, placing them cut sides up and packing them tightly. Pour any remaining juices from the skillet over the tomatoes.
5. Cover the tomatoes with the puff pastry, tucking the edges in to securely encase the filling. Gently prick the dough with a fork to let the air escape during baking. Bake for about 35 minutes, or until the puff pastry is golden brown. Carefully remove the tart from the oven, then run a knife alongside the edges of the tart pan to release the puff pastry.
Place a plate over the top of the tart, then swiftly invert the pan to flip the tart onto the plate. Serve warm garnished with thyme leaves (if using).
Note: Sprinkle with crumbled fresh goat or feta cheese right before serving for extra flavour.
