Making Pizza Pot Pie is a straightforward process. Follow these steps to create a delicious meal:

1. Preheat the Oven: Preheat your oven to 400°F (200°C).
2. Prepare the Filling: In a large bowl, combine the cooked chicken or sausage, pizza sauce, mozzarella cheese, pepperoni slices, and any additional vegetables. Season with salt, pepper, and Italian seasoning.
3. Roll Out the Dough: If using a homemade pie crust, roll it out on a floured surface to fit your pie dish.
4. Assemble the Pie: Place the bottom crust into a pie dish. Pour the filling mixture into the crust, spreading it evenly.
5. Top with Crust: Roll out the second pie crust and place it over the filling. Trim any excess dough and crimp the edges to seal.
6. Cut Vent Holes: Cut a few slits in the top crust to allow steam to escape during baking.
7. Apply Egg Wash: Brush the top crust with the beaten egg for a golden finish.
8. Bake: Bake in the preheated oven for about 30-40 minutes, or until the crust is golden brown and the filling is bubbly.
9. Cool: Remove from the oven and let it cool for 10 minutes before slicing. This helps the filling set a bit.
10. Serve: Slice and serve warm, garnishing with fresh herbs if desired.

By following these steps, you’ll create a flavorful Pizza Pot Pie that is sure to become a family favorite.
