First off, fry the bacon until super crispy, put on some kitchen paper and leave to one side.
Pre heat the oven to 180º.
Dust your work surface with a little flour and roll out the pastry into a large rectangle that is the thickness of a £1 coin. Trim the edges so that they are straight.
Evenly spread the tomato puree over the pastry, leaving a 1cm gap at the edges. Crumble the bacon over the top of the puree and then the cheeses.
Roll the pastry and filling and then brush a little beaten egg on to the edge of the pastry so that the edges stick together.
Slice the roll in 2 cm intervals then place each pin wheel on to a baking sheet. Brush with the beaten egg.
Put in the oven for 15-20 minutes until the pastry is golden brown.
