Preheat the oven to 375 degrees F. Spray a pie plate with non-stick cooking spray or grease with a thin layer of olive oil.

Whisk egg and water together.

Mix together oregano, basil, garlic powder and red pepper flakes.

Roll out pizza dough into a large rectangle using a rolling pin on a lightly floured surface or on a silicone pastry mat. The dough should be pretty thin, less than ¼ inch thick.

Brush dough with egg wash.

Sprinkle spice mix evenly across the dough.

Layer pepperoni slices and mozzarella cheese evenly across the dough, leaving about a ¼ to ½ inch border along all four sides.

Slowly and carefully, tightly roll up the dough jellyroll style.

Pinch the ends of the pepperoni roll closed and use a bit of egg wash to seal the seam across the entire roll.

Coil pepperoni bread, and place it in the prepared pie plate.

Brush the top with egg wash.

Give a light sprinkle of garlic powder and oregano, and dust the top with grated parmesan cheese.

Place in the oven and bake for 30 minutes, or until golden brown.

Let stand for a few minutes before cutting and serving it hot with a side of pizza sauce for dipping.
