A fridge audit revealed some Silly Yak pastry and grated mature cheddar... and an idea was forming.
Using half a pack of Silly Yak gluten free puff pastry, it was rolled out into a rectangle (about 3mm thick). 
The cheese was mixed with a Tablespoonful of paprika and smoked paprika, and a 'generous' sprinkle of chilli flakes. These were then spread over the pastry, patted down and the pastry was rolled from one of the long sides... into a swiss roll shape.
Cutting the pastry roll into slices about 1.5cm thick, they were placed on a non-stick baking sheet and then put in a pre-heated hot oven (180C) for 10 minutes; they were checked and cooked for another 2 minutes until crisp and bubbling. 
Cooling them on the baking tray for a few minutes, they were removed and allowed to cool completely.
