Prepare the Filling: Drain and squeeze the moisture from thawed spinach, then mix it with mozzarella, parmesan, garlic powder, onion powder, and salt in a bowl.

Roll Out the Puff Pastry: Roll out thawed pastry sheets on a floured surface, then spread the spinach and cheese mixture onto it, leaving a half-inch border.

Form the Rolls: Roll the pastry tightly from one edge, slice into 1 to 1¼ inch rounds, and place cut-side up on a parchment-lined baking sheet.

Chill the Rolls: Refrigerate the rolls for about 15 to 20 minutes to maintain shape during baking.

Preheat the Oven: Preheat the oven to 400°F (200°C) for golden, crispy rolls.

Apply the Egg Wash: Whisk an egg with water and brush it over the tops of the rolls.

Bake to Perfection: Bake the rolls for 18 to 22 minutes until golden brown.

Serve and Enjoy: Allow to cool slightly before serving with dipping sauces.
