Spread the dough out on a buttered cookie sheet, like a pizza crust.
Mix the other ingredients (minus the fillings) and spread like butter on the crust.
Layer the fillings and top with cheese.
Roll it up starting with the long edge so you end up with a long, log shape.
Place it seam side down on the cookie sheet.
Brush with the reserved egg white.
Bake at 350 degrees for 30-40 minutes.
Slice and serve with the pizza sauce.
