1. Prepare the Puff Pastry:
   • Preheat the oven to 180°C (356°F).
   • Roll out the puff pastry to your desired thickness on a lightly floured surface.
   • Spread 50g of mustard evenly over the pastry.
2. Add the Fillings:
   • Layer 200g of ham evenly on the pastry.
   • Sprinkle 200g of grated or thinly sliced cheese on top of the ham.
3. Fold and Seal:
   • Fold the puff pastry over the filling to form a sealed pocket or roll.
   • Brush the top with beaten egg for a glossy finish.
4. Bake the Pastry:
   • Place the pastry on a baking sheet lined with parchment paper.
   • Bake for 20 minutes or until golden and puffed.
5. Prepare the Béchamel Sauce:
   • Melt 30g of butter in a saucepan over medium heat. Add 25g of flour and whisk until smooth.
   • Gradually add 300ml of milk, whisking to prevent lumps. Cook until thickened.
   • Stir in nutmeg, black pepper, salt, and Parmesan cheese until smooth.
6. Finish and Serve:
   • Let the baked pastry cool slightly on a wire rack.
   • Serve warm, drizzled with béchamel sauce or with the sauce on the side for dipping.
   • Garnish with finely chopped pickled cucumbers for a tangy crunch.
