Making Easy Ham and Cheese Pinwheels with Puff Pastry is a breeze if you follow these simple steps:

1. Preheat the oven to 400°F (200°C) and line a baking sheet with parchment paper.
2. Prepare the pastry: Roll out the thawed puff pastry sheet on a lightly floured surface until it’s slightly larger.
3. Spread the mustard (if using) evenly over the pastry to enhance the flavors.
4. Layer the filling: Sprinkle the chopped ham and shredded cheese evenly over the pastry, leaving a small border around the edges.
5. Season with salt, pepper, and any additional herbs you desire.
6. Roll the pastry tightly into a log, starting from one end and rolling towards the other. Ensure it’s sealed well at the edges.
7. Slice into pinwheels: Cut the log into 1-inch thick slices and place them on the prepared baking sheet.
8. Brush with egg wash: Using a pastry brush, coat the tops of the pinwheels with the beaten egg for a golden finish.
9. Bake for 15-20 minutes or until they are golden brown and puffed.
10. Cool slightly before serving, then enjoy these delicious bites!
