Baked brie and wild mushroom tart

Method

1. Melt the butter in a large frying pan, add the sliced mushrooms and fry over a high heat for 2-3 minutes. Reduce the heat, add the garlic and rosemary, season and fry for 1-2 minutes, then leave to cool.
2. Place the spinach in a colander and pour over a kettle of boiling water to wilt, then refresh under the cold tap. Squeeze to remove all the excess water.
3. Unroll 1 sheet of pastry onto a non-stick baking sheet, scatter with the cooked spinach, leaving a 2cm border, then cover with the cooled mushroom mix and finally the sliced brie. Brush the edges of the pastry with some of the beaten egg. Lay the second sheet of pastry over the filling and press with your fingers to remove any air pockets, then seal the edges well with a fork.
4. Score the top of the pastry lightly with the back of a sharp knife, chill for 20 minutes, and preheat the oven to 200°c/fan180°c/gas 6.
5. Brush the pastry with the remaining beaten egg and bake for 15-20 minutes until golden brown and crisp. Cut into 4-6 squares, and serve with a crisp green salad.
