Preheat the oven to 200°C. Thaw your puff pastry as per the package instructions and dust your board or counter with flour. To save time you can do this straight onto a baking sheet lined with parchment paper too.
Place the puff pastry on top and fold all the edges about a quarter inch towards the middle. Take a fork and dip it in flour and a crimp the edges all around. In a separate bowl whisk one egg with a little bit of water and brush it all around the border.
To make the filling add the mozzarella, egg, feta, and spinach into a separate bowl and mix it together. Add the filling to the middle of your pastry and spread it in the middle within the square with a spoon.
Bake at 200C for 20-25 minutes or until golden.
Optionally, broil the top for about a minute but watch it the whole time. Enjoy!
