Preheat your oven to 425°F.
Line your baking sheet with parchment paper.
Dust your counter with flour lightly.
This prevents dough from sticking.
Combine ricotta, mozzarella, and Parmesan in a bowl.
Add the cooked sausage and pepperoni.
Sprinkle garlic powder and Italian seasoning.
Mix everything well with a spoon.
Season with salt and pepper.
Cut pizza dough into 4 equal pieces.
Roll each piece into a circle.
Make them about 8 inches wide.
Keep edges slightly thicker than the center.
Place filling on one half of each circle.
Leave a 1-inch border around edges.
Don't overfill or they'll burst open.
Less is more with calzones.
Fold dough over the filling carefully.
Press edges together with your fingers.
Use a fork to crimp the edges.
This creates a tight seal.
Brush each calzone with beaten egg.
This creates a golden crust.
Cut small slits on top for steam.
Place them on your baking sheet.
Bake for 15-18 minutes until golden brown.
Watch them carefully near the end.
Remove when they're crispy and beautiful.
Let them cool for 5 minutes.
