Puff pastry strudel with ham and cheese, absolutely dangerous!

Preheat Oven: Preheat your oven to 200°C (400°F) and line a baking sheet with parchment paper.
Prepare Puff Pastry: Roll out the puff pastry on a lightly floured surface to remove any creases and make it a bit thinner.
Add Mustard (Optional): If using mustard, spread a thin layer over the puff pastry, leaving a border of about 1 inch around the edges.
Layer Ham and Cheese: Evenly distribute the sliced ham over the mustard (or directly on the pastry if not using mustard). Sprinkle the shredded cheese evenly over the ham.
Season and Roll: Season with freshly ground black pepper. Carefully roll up the puff pastry from one of the long sides to form a log. Pinch the seams and ends to seal the strudel.
Egg Wash: Place the strudel seam-side down on the prepared baking sheet. Brush the top and sides with the beaten egg to give it a golden, glossy finish. If desired, sprinkle sesame seeds or poppy seeds on top.
Bake: Bake in the preheated oven for 25-30 minutes, or until the pastry is puffed up and golden brown.
Cool and Slice: Allow the strudel to cool for a few minutes before slicing it into pieces. Serve warm.

You can add some sautéed mushrooms, spinach, or caramelized onions for extra flavor.
This strudel is best enjoyed fresh out of the oven, but it can also be reheated in a 350°F (175°C) oven for about 10 minutes if you have leftovers.
