Cooking Steps

• Preheat your oven to 400°F (200°C).
• On a lightly floured surface, roll out the puff pastry sheet to smooth out any creases, aiming for a rectangle of about 12×15 inches.
• Layer the thinly sliced ham evenly over the puff pastry, leaving a small border around the edges.
• Place the slices of cheese on top of the ham in a single layer.
• If using, spread the Dijon mustard evenly over the cheese for added flavor.
• Sprinkle some freshly ground black pepper over the top to your liking.
• Starting from one edge, carefully roll the pastry tightly into a log.
• Once rolled, use a sharp knife to slice the log into 1-inch thick rounds, yielding about 12-15 pinwheels.
• Lay the pinwheels cut side up on a parchment-lined baking sheet.
• Brush the tops of the pinwheels with the beaten egg.
• Bake in your preheated oven for 15-20 minutes or until the pinwheels are puffed up and golden brown.
• Once baked, remove from the oven and allow them to cool for a few minutes before serving.
