Preheat the oven to 375° F. Unfold the puff pastry sheet on a piece of parchment paper. Combine the mustard, honey, and dill in a small bowl. Brush the honey mustard mixture onto the pastry sheet. Layer the ham slices over the length of the puff pastry. Sprinkle the cheddar cheese over the ham. Using the parchment paper to lift it, roll the pastry into a tight spiral. The roll can be placed in the freezer for 15 minutes at this point to make cutting easier, or if you’re in a hurry, just go for it. Using a sharp, serrated knife, cut the log into 12 even slices. Place the pinwheels flat on a parchment-lined baking sheet, reshaping them a bit into rounds if necessary. Sprinkle with the parmesan cheese.
