1. Preheat the oven to 400°F (200°C). Line a baking sheet with parchment paper.
2. Roll out the puff pastry on a lightly floured surface and cut it into 6 equal rectangles.

Assemble the Pockets:

1. Spread a thin layer of Dijon mustard or mayonnaise on one half of each rectangle (optional).
2. Add a layer of ham and sprinkle grated cheese on top. Season with black pepper if desired.
3. Fold the other half of the puff pastry rectangle over the filling to create a pocket.
4. Seal the edges by pressing with a fork, ensuring the filling stays inside.

Bake:

1. Transfer the pockets to the prepared baking sheet. Brush the tops with beaten egg for a golden finish.
2. Bake in the oven for 18-20 minutes, or until the puff pastry is golden and crispy.
3. Let cool slightly before serving.

Serving Suggestions

• Serve with a side salad for a complete meal.
• Pair with ketchup, honey mustard, or a creamy garlic dip for extra flavor.

Cooking Tips

• Add herbs like parsley or chives for an extra burst of flavor.
• For a spicier kick, add a pinch of chili flakes or a slice of jalapeño.
• Ensure the edges are well-sealed to prevent the cheese from leaking during baking.
