Directions
Preheat your oven to 400°F (200°C) and line a baking sheet with parchment paper.
Lightly dust your work surface with flour and roll out the puff pastry sheet to smooth any creases.
Spread the Dijon mustard evenly over the pastry sheet.
Layer the ham slices over the mustard, ensuring they cover the entire surface.
Sprinkle the shredded cheese evenly over the ham.
Starting from one edge, carefully roll the pastry into a tight log.
Using a sharp knife, slice the log into 1/2-inch thick pinwheels.
Place the pinwheels on the prepared baking sheet, leaving space between each.
Brush the tops with the beaten egg to give them a golden finish.
Bake in the preheated oven for 15-20 minutes, or until the pinwheels are puffed and golden brown.
Allow to cool slightly before serving.
