# Ingredient List:
→ Pastry
01 - 1 sheet ready-rolled puff pastry (approx. 8.8 oz; chilled, not frozen)
→ Filling
02 - 3.5 oz thinly sliced cooked ham
03 - 3.5 oz grated cheddar cheese or Swiss cheese
04 - 2 teaspoons Dijon mustard (optional)
05 - Freshly ground black pepper to taste
→ For Baking
06 - 1 egg, beaten (for egg wash)
# How to Make:
01 - Preheat the oven to 400°F and line a baking sheet with parchment paper.
02 - Unroll the puff pastry sheet onto a lightly floured surface.
03 - Spread Dijon mustard evenly over the pastry surface, if using.
04 - Arrange ham slices evenly over the mustard-covered pastry, leaving a 0.4-inch border along one long edge.
05 - Sprinkle grated cheese evenly over the ham and season lightly with freshly ground black pepper.
06 - Starting from the long edge without the border, tightly roll up the pastry into a log, sealing the edge with a little beaten egg.
07 - Using a sharp knife, cut the log into 16 equal slices.
08 - Place pinwheels cut-side up on the prepared baking sheet, spaced slightly apart, then brush the tops with the beaten egg.
09 - Bake for 18 to 20 minutes or until pinwheels are golden brown and crisp.
10 - Allow to cool slightly before serving warm or at room temperature.
