Preheat oven to 450℉. Prepare baking sheet with parchment.

Divide dough into 8 equal pieces and roll each one out into a circle on a floured surface.

In a large bowl mix spinach, ricotta, mozzarella, parmesan, basil, salt, pepper and chili flakes.

Divide the mixture evenly between the 8 circles of dough, keeping the filling to one side.

Fold dough over the filing and use your fingers to pinch and crimp the edges together.

Place the calzones on prepared sheet.

Cook for 10-15 minutes on the bottom of preheated oven until dough is puffed up and golden on top.

Serve with your favorite all-natural marinara.
