Preheat oven to 400ºF (204ºC). Set aside a baking sheet lined with parchment paper.
On a lightly floured surface, roll the dough out into a 10x14 inch (25x35 cm) rectangle. You can use store-bought dough or make your own pizza dough. See recipe notes below for homemade pizza dough recipe.
Brush the surface with olive oil. (This will prevent your rolls from getting soggy.)
Spread marinara sauce on top of the dough. Leave a gap of about 1 inch (2.5cm) around the edges, you don’t want to spread your sauce all the way to the edge.
Sprinkle with mozzarella and then top with pepperoni.
Starting with the long end, carefully roll the dough into a tight log. Make sure you roll your dough very tightly so that they won’t fall apart when you slice them into smaller pieces.
Place the log seam side down and slice it into 1-inch (2.5 cm) pieces.
Place rolls on baking sheets lined with parchment paper. (It is important to use parchment paper so that the rolls won’t stick to the baking sheet)
Arrange them 1 inch (2.5 cm) apart in a single layer.
Brush the rolls with egg wash. This will make rolls golden brown when they are baked.
Bake for about 10-15 minutes or until browned on top.
Let cool for 5 minutes. Sprinkle with chopped parsley and grated parmesan cheese if desired.
Serve warm with marinara or ranch sauce for dipping.
