Creating Pizza Pot Pie is a simple and fun process. Just follow these steps to ensure you achieve a delicious result:

1. Preheat the Oven: Preheat your oven to 425°F (220°C).
2. Prepare the Pie Crust: Unroll the pie crust and fit it into a 9-inch pie pan. Trim any excess overhang.
3. Mix the Filling: In a large bowl, combine pizza sauce, shredded mozzarella cheese, sliced pepperoni, assorted vegetables, Italian seasoning, salt, and pepper. Mix until well combined.
4. Fill the Pie: Pour the pizza filling mixture into the prepared pie crust, spreading it evenly.
5. Cover with Second Crust: Unroll a second pie crust on top of the filling. Seal the edges by crimping with a fork or your fingers.
6. Cut Steam Vents: Cut a few slits in the top crust to allow steam to escape during baking.
7. Apply Egg Wash: Brush the top of the crust with the beaten egg for a golden finish.
8. Bake: Place the pie in the oven and bake for 35-40 minutes, or until the crust is golden brown.
9. Cool Slightly: Remove from the oven and let it cool for about 10 minutes to set before slicing.
10. Serve: Cut into wedges and serve warm, complete with a side of extra pizza sauce for dipping, if desired.

Follow these step-by-step instructions, and you’ll create a delightful Pizza Pot Pie that’s both tasty and visually appealing.
