Directions

Preheat your oven to 425°F (220°C).
On a floured surface, divide the pizza dough into four equal portions and roll each into a circle about 8 inches in diameter.
In a bowl, combine the diced ham, mozzarella, ricotta, Parmesan, oregano, and garlic powder.
Place a quarter of the filling on one half of each dough circle, leaving a border around the edge.
Brush the edges of the dough with the beaten egg, then fold the dough over the filling to create a half-moon shape. Press the edges with a fork to seal.
Transfer the calzones to a baking sheet lined with parchment paper.
Brush the tops with olive oil and make a small slit in the top of each calzone to allow steam to escape. Top with more cheese if desired.
Bake in the preheated oven for 15-20 minutes, or until golden brown.
Allow to cool slightly before serving.

Variations & Tips
For a bit of a kick, try adding a pinch of red pepper flakes to the filling. You can also swap out the ham for turkey or cooked sausage for a different flavor. If you have some fresh herbs on hand, like basil or parsley, chop them up and mix them into the filling for an extra burst of freshness. And if you’re feeling adventurous, a spoonful of marinara sauce inside each calzone can add a delightful twist.
