Ingredients:
1 10 by 10 inch puff pastry sheet
A bit of flour for dusting your board. This step is optional but helpful
⅓ cup grated mozzarella
100 grams feta
1 egg
¾ cup of frozen thawed spinach (squeeze the water out)
Instructions:
Preheat the oven to 400°F (200°C).
Thaw your puff pastry as per the package instructions and dust your board, counter, or 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 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 400F (200°C) for 20-25 minutes or until golden.
*Optionally broil for 1 minute on top but watch it the whole time.
Note: I docked my pastry before baking it. The steam needs to escape from somewhere while your puff pastry is in the oven.
Enjoy!
