Preheat the oven to 400 degrees F. Spray a 12-count muffin pan with nonstick cooking spray.
Unroll the pizza dough onto a floured work surface. Using a rolling pin, roll out the dough slightly so that it is a uniform rectangle about 11 inches by 15 inches.
Slice the pizza dough widthwise into twelve 1 1/2-inch-wide strips. Separate the strips on the work surface. Spread a thin layer of pizza sauce onto each strip and sprinkle with a thin layer of cheese. Place about 7 slices of pepperoni slightly overlapping down the center of each pizza dough strip so that the top halves of the pepperoni slices hang over the edge of the dough strip. Carefully roll up each strip into a tight roll so it looks like a rose bud, then transfer to the prepared muffin pan.
Bake until the crust is golden and the pepperoni is slightly crispy, 15 to 18 minutes. Let cool in the pan about 3 minutes. Serve warm.
To make a pizza rose bouquet, insert wooden skewers in the base of a potted basil plant, then attach a pizza rose to the end of each skewer.
