Follow these easy steps to make your Ham and Cheese Puff Pastry Sticks:

1. Preheat the Oven: Preheat your oven to 400°F (200°C) and line a baking sheet with parchment paper.
2. Prepare the Puff Pastry: On a lightly floured surface, roll out the thawed puff pastry sheet to ensure it’s smooth and even.
3. Cut the Pastry: Cut the puff pastry into rectangles, approximately 2 inches by 6 inches, to form your sticks.
4. Add Mustard (Optional): Spread a thin layer of Dijon mustard on each pastry rectangle for extra flavor.
5. Layer the Fillings: Place a slice of ham on each rectangle, followed by a generous sprinkle of shredded cheese.
6. Seal the Pastry: Fold the pastry over to form a stick shape and press the edges lightly to seal them closed.
7. Apply Egg Wash: Brush the tops of the pastry sticks with the beaten egg to ensure a golden color when baked.
8. Bake: Place the prepared sticks on the baking sheet. Bake in the preheated oven for 15-20 minutes, or until they are puffed and golden brown.
9. Cool Slightly: Remove the baking tray from the oven and let the sticks cool for a few minutes before serving.
