Pepperoni Pinwheels

Preheat the oven to 400°F. Line a baking sheet with parchment paper.
In a small bowl, add the egg and water. Mix until combined. Set aside.
Unfold the defrosted puff pastry onto a flat surface.
Using a pastry brush, coat the puff pastry with the egg wash. Set aside the remainder of the egg wash.
Cover the puff pastry with 1/4 cup of marinara sauce or pizza sauce. Leave 1/2 inch on all sides.
Top the sauce with mozzarella cheese, pepperoni, Italian seasoning, and garlic powder.
Roll the puff pastry like a jelly roll. Then, place the roll in the freezer for 10 minutes.
With a serrated knife, cut off the ends of the roll and discard. Then cut the remainder of the roll into 1-inch slices. You will have approximately 15 slices.
Place the slices on a baking sheet lined with parchment paper. Using a pastry brush, coat the top of the slices with the egg wash.
Sprinkle half of the parmesan cheese on top of the slices Bake for 15-20 minutes or until golden brown.
Top with the remainder of the parmesan cheese and parsley. Serve with the remainder of the marinara sauce.
