Bake in the preheated oven for 15-20 minutes, or until golden brown.
Allow to cool slightly before serving.
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.
