Preheat the oven to 350°F. Prepare the pizza dough according to the package directions.
On a lightly floured surface, roll out each portion of dough into a large rectangle, about 12x8 inches.
In a small bowl, whisk together the egg yolks, Parmesan cheese, oregano, parsley, garlic powder, black pepper, and olive oil until combined.
Spread the egg yolk mixture evenly over the surface of each rolled-out pizza dough, leaving a ½-inch border around the edges.
Arrange the pepperoni slices in an even layer on top of the egg mixture. Sprinkle the shredded mozzarella cheese over the pepperoni.
Starting at one of the long sides, carefully roll up each rectangle into a tight log, pinching the seams to seal. Place the logs seam-side down on a parchment-lined baking sheet.
Brush the reserved egg whites over the top and sides of each stromboli. Cut a few diagonal slits in the top to allow steam to escape during baking.
Bake for 20-25 minutes, until the crust is golden brown and the cheese is melted and bubbly. Let cool for 5 minutes before slicing.
Slice the stromboli into 1-inch pieces and serve warm with marinara sauce for dipping, if desired. This recipe makes 2 stromboli, about 12 slices each. Enjoy!
