Preheat oven to 400 degrees F. Unroll pizza dough onto work surface with the long side parallel to the edge of the counter. Cut into 12 equal strips, about 1 ½-2 inches wide. Spread pizza sauce over dough, then sprinkle over parmesan cheese, mozzarella cheese and Italian seasoning.
Working with one strip at a time, place 7-8 slices pepperoni down each strip of dough, overlapping slightly. The top of the pepperoni should stick out over the top of the dough. Roll the dough into a cylinder to look like a rose bud and transfer to a 12-well muffin tin with the pepperoni edge up.
Bake for 15-20 minutes until golden and and crisp. To serve, place a skewer in the bottom of each pizza rose and tie together.
