Preheat oven to 375°F (190°C). Grease a baking dish or line with parchment paper.

Roll out the pizza dough into a rectangle on a lightly floured surface.

Evenly layer ham slices over the dough, followed by shredded Swiss cheese.

Roll up the dough tightly, starting from the longer edge, forming a log.

Slice the roll into 1-inch thick rounds and place them in the prepared baking dish.

In a small bowl, mix melted butter, Dijon mustard, Worcestershire sauce, poppy seeds, garlic powder, and onion powder.

Brush the butter mixture over the tops of the pinwheels.

Bake for 18-22 minutes, or until golden brown and bubbling.

Remove from oven and let cool slightly before serving.
