2. Gently saute the onion in a little olive oil until just cooked
3. Once cool, coarsely chop the spinach and mix really well with feta and other ingredients by hand in a large mixing dish until you have a thick batter
4. Lay out one sheet of pastry and egg wash all around the sides
5. Place your filling in the centre and carefully push out to the edges but not all the way you leave a 1 inch rim of pastry showing
