Place the pastry on a large oven tray lined with non-stick baking paper. Using a small sharp knife, gently score a 2cm border around the edge of the pastry and prick the centre with a fork.
Top the pastry with the mozzarella, mushrooms & truffle brie
Cook for 18–20 minutes or until the cheese is bubbling and the pastry is golden and cooked on the base.
Drizzle with sticky balsamic truffle to serve and a little rocket. Serves 8
