Prepare the crust:
Preheat the oven to 375°F (190°C).
Roll out the pie crust and place it into a deep pie dish. Brush the crust with olive oil. Pre-bake the crust for about 8 minutes, then remove it from the oven and set it aside.
Make the filling:
In a large skillet, heat olive oil over medium heat. Add onion and garlic, and sauté until translucent.
Add sausage and cook until browned and crumbled. Drain any excess fat.
Stir in pizza sauce, mozzarella cheese, pepperoni, bell peppers, mushrooms, Italian seasoning, salt, and pepper. Cook until everything is well combined and the cheese starts to melt.
Assemble the pie:
Spoon the filling into the pre-baked crust. Top with extra mozzarella cheese and pepperoni slices.
Optionally, cover with another layer of pie crust, sealing the edges and cutting slits to allow steam to escape.
Bake:
Bake in the preheated oven for 25-30 minutes, or until the crust is golden brown and the filling is bubbly.
Let cool for a few minutes before serving.
