Pre-heat oven to 350 degrees. Spray 10"x14" cookie sheet (or similar size). Lay the pizza crust dough on the sheet and, with your fingers, gently stretch to fit, or almost fit, the pan (try not to make holes). Down the center (the long way) lay a row of pepperoni 3 or 4 slices wide overlapping as you go from one end to the other. Top the meat with the cheese, sprinkle lightly with Italian seasonings. Carefully pull one side up and over the meat and cheese, then pull the other side over that to completely cover the meat and cheese. Spray the top with cooking spray, sprinkle lightly with garlic salt and Italian seasoning. Bake for 15-20 minutes or until desired degree of brown is reached.

Remove from oven and let sit for 5 minutes. Slice into 1-1 1/2-inch slices. Serve with marinara dipping sauce if desired.
