Preheat your oven to 375°F (190°C). On a lightly floured surface, roll out your crescent dough into a rectangular shape and cut it into rectangles for filling.

In a mixing bowl, combine shredded mozzarella cheese, your choice of toppings, and marinara sauce. Mix well until combined.

Spoon filling onto each dough rectangle, fold over, and seal the edges firmly. Use a fork to crimp the edges and cut slits on top for steam.

Arrange on a baking sheet lined with parchment and bake for about 15 minutes until golden brown and puffed.

Let cool for a few minutes before serving with additional marinara sauce for dipping.
