Preheat oven to 400°F (200°C). Line a rimmed baking sheet with parchment paper.
02 -
On a lightly floured surface, roll the puff pastry into a rectangle, approximately 10 x 12 inches, if necessary.
03 -
Spread Thousand Island dressing evenly over the pastry, leaving a 1/2-inch border. Distribute Swiss cheese evenly over the dressing, then add a layer of chopped corned beef and evenly scatter the well-drained sauerkraut on top.

Tightly roll up the pastry from the long edge into a log. Pinch the seam to seal. Using a sharp knife, cut the log into 1/2-inch thick slices.
05 -
Place the slices cut-side up on the prepared baking sheet, spacing them apart. Brush each pinwheel with beaten egg and sprinkle with caraway seeds if desired.
06 -
Bake for 15–18 minutes until the pastries are puffed and golden brown. Let cool slightly on the tray. Garnish with chopped fresh parsley before serving.
