Spinach, bacon & roquefort tart

Heat the oven to 200C/180C fan/gas 6. Roll out the pastry onto a lined baking sheet. Using the tip of a sharp knife, mark a 2cm border around the edge. Brush the pastry all over with the egg and bake for 10 mins. Leave for 5 mins, then press down the centre with your hands, leaving the border. Top with the spinach, tomatoes and roquefort, and return to the oven for 10-15 mins. Meanwhile, fry the bacon until very crispy. Drain and chop or break into shards and scatter over the tart.
