Place the spinach in a microwave safe bowl and microwave for one minute on high. If the spinach is not completely reheated, stir it and microwave again for 30 seconds.
Drain the spinach.
In a bowl, combine all filling ingredients and set aside.
Prepare the egg wash: crack an egg into a bowl and beat it thoroughly with a fork, add two tablespoons of water, a pinch of salt and stir until combined. Set aside (optional, for a golden sheen).
Melt the shredded mozzarella & add the almond flour. Stir until well-combined. Roll the dough out between 2 sheets of parchment paper.
Gently add the fillings on to one side of the dough, fold it over and seal the dough. Brush with egg wash if using.
Bake for about 20-25 minutes or until it turns golden and firm to the touch. Remove from oven and enjoy!
