Preheat your oven to 350°F. Lightly spray a 9 inch pie plate or 7 x 11 inch baking dish with non-stick cooking spray and set aside.
In a mixing bowl combine the cream cheese, sour cream, and 1 teaspoon of the Italian seasoning. Spread the mixture into the prepared pie plate.

Top the cream cheese mixture with the pizza sauce (or marinara sauce if you are using that).
1 cup pizza sauce
Sprinkle the mozzarella cheese over the pizza sauce and top with your desired amount of pepperoni slices.
8 ounces shredded mozzarella cheese, 15 Pepperoni slices
Bake for 15 to 20 minutes or until the cheese is completely melted. If you prefer, you can broil the dip for 2-3 minutes to brown the cheese slightly.
Sprinkle with the remaining ½ teaspoon Italian seasoning and grated Parmesan cheese.
⅓ cup Parmesan cheese, ½ teaspoon Italian seasoning
Serve warm with your choice of dippers.
