Spoon the pasta sauce on top and evenly spread a thin layer using the back of a spoon leaving a 1cm border.
Evenly line pepperoni slices on top of the sauce then sprinkle grated cheese on top. Do not cover the border area with toppings, keep this section clear.
Roll the puff pastry sheet tightly starting with the longest side. Seal by gently pressing the dough at the end.
Place in the fridge for 10 minutes, in the meantime preheat your oven to 200°C (gas mark 6, 400°F).
With a sharp knife, cut the pizza roll into 12 equal slices. They should be around 1.5cm each.
Place the pizza wheels onto a lined baking tray. Whisk an egg and brush the pastry with the beaten egg.
Place in the oven for 13 to 15 minutes or until the pastry is golden and the cheese has melted.

Notes
Top Tip: Before you start this recipe, take the pastry out of the fridge to thaw for 15 minutes. This prevents the pastry from breaking apart whilst unrolling.
