Caramelised onion pastry pizzas

Method

1. Preheat the oven to 200°C/fan180°C/gas 6. Lay out the pastry sheets on a work surface and cut out an 18cm circle (see tip, below) from each one.
2. Transfer to a large lined baking sheet and spread the caramelised onions evenly over each circle. Scatter with the thyme, then transfer to the oven to cook for 15-20 minutes until the pastry is slightly puffed, golden and cooked. Remove, then divide the Parma ham, goat’s cheese and watercress between the two pizzas. Grind over plenty of black pepper, then serve.
