Rinse the spinach well and place in a colander. Pour 2 kettles of freshly boiled water over the spinach to wilt. Allow to cool a little and squeeze all the excess water. Chop and set aside
Mix the spinach, ricotta, feta, parmesan and salt and pepper together
Roll out the pastry, just a little, on a flat surface dusted with flour.

Sprinkle the mozarella cheese on top. Roll into a swiss roll shape, lengthwise. Not too tightly

Enjoy warm!
