Preheat your oven to 375°F (190°C) and let your pie dough soften at room temperature. Press the dough into a deep-dish pan, pricking the bottom to prevent bubbles, and pre-bake for 10 minutes.

Heat a tablespoon of olive oil in a skillet over medium heat. Add ground beef and sausage, seasoning with salt and pepper, and cook for 7–10 minutes until browned. Drain excess grease.

Spread pizza sauce over the pre-baked crust, sprinkle half of the mozzarella cheese on top, then layer the meat mixture, more pizza sauce, the remaining cheese, pepperoni, and Parmesan.

Bake in the oven for 25–30 minutes until the cheese is bubbly and golden brown.

Let the pie cool for 5–10 minutes before slicing. Garnish with fresh parsley before serving.
