Preheat your oven to 350°F (175°C) and prepare a 9x13 inch baking pan by coating it with cooking spray.

Unroll the pizza dough onto a lightly floured surface and roll it into a 13x8 inch rectangle.

Layer the ham evenly across the dough surface, followed by Swiss cheese slices.

Tightly roll the dough from one long side into a log shape and pinch the ends to seal.

Slice the rolled dough into 12 even pieces, about 1 inch thick, and arrange them in the baking pan.

Mix the melted butter, brown sugar, Dijon mustard, and poppy seeds in a small bowl until smooth.

Drizzle the butter mixture over the pinwheels and bake for 25-30 minutes until golden brown.

Let cool slightly, optionally sprinkle with chopped parsley, and serve warm.
