Preheat your oven to the temperature indicated on the Crescent Roll Dough package.

Combine the filling by mixing chopped artichoke hearts, fresh spinach, sour cream, mayonnaise, garlic powder, onion powder, salt, and pepper in a large bowl.

Roll out the dough and spread the spinach and artichoke mixture evenly across it.

Sprinkle the mozzarella and Parmesan over the filled dough.

Roll the dough into a tight log and slice into pinwheels, about one inch thick.

Arrange the pinwheels on a parchment-lined baking sheet.

Bake according to the package instructions until golden brown and cheese is bubbly.

Serve warm with marinara sauce for dipping.
