Fire up your oven to 375°F.
Mix your filling ingredients in a large bowl.
Roll out that pizza dough into a rectangle about 12×16 inches.
Spread your filling mixture evenly, leaving a 1-inch border.
Roll it up like a jelly roll, starting from the long side.
Place it seam-side down on your baking sheet and brush with beaten egg.
Pop it in the oven for 25-30 minutes until it’s gloriously golden brown.
Let it rest for 5 minutes before slicing.
Serve with warm marinara sauce on the side for dipping.
