Preheat your oven to 375°F (190°C). Prepare your pie crust by rolling it out on a floured surface, then place it in a pie dish, pressing gently against the sides.

In a large skillet over medium heat, cook the ground beef and Italian sausage for about 8-10 minutes, breaking it up as it cooks. Drain any excess grease.

Combine the cooked meats with the pepperoni and pizza sauce in a large mixing bowl, stirring until well-coated.

Spoon the meat mixture into the pie crust and sprinkle mozzarella cheese on top, covering the mixture entirely.

Bake the pie in the preheated oven for 30-35 minutes, until the crust is golden brown and the cheese is bubbling.

Remove the pie from the oven and allow it to cool for 10-15 minutes before slicing and serving warm.
