  1. Roll out the pastry on a floured counter and cut out four, 5 inch (13cm) squares. Chill in the fridge for 30 minutes. Place a baking sheet ( or 2) in the oven and heat the oven to 425 degrees F.
  2. Meanwhile, heat 3 tbsp oil in a skillet. Add the onions and cook gently for 30 minutes, until caramelized. Remove from the skillet to a bowl.
  3. Heat the remaining oil in the skillet. Add the mushrooms and cook at high heat until soft and most of the liquid has evaporated. Stir in the onions and then the pine nuts, oregano. Season these ingredients with salt and pepper.
  4. Place the chilled pastry squares on the baking sheets. Prick the squares with a fork and brush with oil. Divide the mushroom mixture between them, leaving a half-inch margin if possible. Place the cheese slices on top. Bake for 15 minutes until the pastry is golden and the cheese is melted.
