Pre-heat the oven to 200C (390F). Line a baking sheet with baking parchment.
Mix the passata with a pinch of dried oregano and mix to combine.
Spread the tomato passata over the sheet of pastry and lay over slices of prosciutto. Add crumbled pieces of Gorgonzola cheese on top followed by the mozzarella.
Roll the pastry up into a log and cut the pastry into 1 inch thick slices (removing the ends with not much filling). Use a sharp knife for this so it’s easier.
Tip: if you find your pastry has got too soft put it back into the fridge or even the freezer to chill and firm up a bit again before slicing.
Place the pinwheels on the baking sheet and brush with beaten egg. Bake in the oven for 25 minutes.
