Preheat your oven to 180°C (350°F) and line a muffin tray with parchment paper.

Roll out the puff pastry on a clean surface.

Layer the sliced ham evenly over the pastry, followed by grated cheddar cheese.

Sprinkle chili flakes, dried oregano, salt, and pepper over the top.

Roll the pastry tightly into a log and slice it into 12 even pieces.

Place each pinwheel into the muffin tray and brush the tops with beaten egg.

Bake for 15-20 minutes or until golden brown and puffed up.

Remove from the oven, let cool slightly, and serve warm.
