Creating Ham and Cheese Puff Pastry Sticks is straightforward. Just follow these steps for a perfect result:

1. Preheat Oven: Begin by preheating your oven to 400°F (200°C). Line a baking sheet with parchment paper.

2. Prepare Puff Pastry: Roll out the thawed puff pastry sheet on a lightly floured surface. Cut it into rectangles, approximately 2 inches by 4 inches.

3. Add Flavor: Optional: Spread a thin layer of Dijon mustard onto each rectangle for added taste.

4. Layer Ingredients: Place a slice of ham and a slice of cheese on one half of each rectangle, leaving space at the edges.

5. Fold: Fold the other half of the pastry over the filling to create a pocket. Press the edges to seal tightly. You can use a fork to crimp the edges for added security.

6. Apply Egg Wash: Brush the tops of the pastry sticks with the beaten egg to promote browning.

7. Sprinkle: Optional: Sprinkle sesame seeds on top of the egg-washed pastry for extra crunch.

8. Bake: Place the prepared pastry sticks on the lined baking sheet and bake in the preheated oven for 15-20 minutes or until golden brown.

9. Cool: Once baked, remove the sticks from the oven and allow them to cool for a few minutes before serving.

10. Serve: Arrange the puff pastry sticks on a platter and enjoy them warm!
