Preheat the oven to 350 degrees Fahrenheit.

Prepare the baking pan by lining it with parchment paper.

Lightly dust a clean working surface with flour.

Unroll the puff pastry dough onto the work surface and roll the dough into a rectangle shape.

Spread a thin layer of the cream cheese over the rectangle, making sure to leave about a 1-inch border of the puff pastry uncovered on each side.

Cover the cream cheese spread with Swiss Cheese slices.

Roll up the puff pastry rectangle tightly, sealing the edges like a jelly roll.

Slice the roll into ¼ inch slices and place on the prepared baking sheet.

Bake for about 15-20 minutes until the slices puff up and are slightly browned.

Serve warm.
