Blend all the ingredients in a food processor until they form a ball. Remove it from the bowl, pat it and smooth it out, cover with plastic wrap and let it rest in the fridge for about 1 hour.
Constructing the pie:
Preheat your oven to 180 deg C and oil a baking dish (mine measured 25cm W x 35cm L)
Divide your pastry into two and roll out to measure the length of the pan. Place one quantity of the rolled pastry onto a lightly oiled baking dish, ensuring it fits well and comes up the sides.
Combine the cheeses, salt, pepper and eggs in a large bowl and then toss through the remaining and mix well, ensuring the mixture =is evenly distributed. (using your hands makes this part a lot easier).
Place the greens mixture into the dish with the pastry and ensuring it all fits. (Don't be afraid to force it all in there!)
Lay the second rolled piece of pastry over the greens mixture and pinch the sides over to encase the mixture. Pierce the top with a sharp knife making some vents.
Brush the top generously with olive oil and bake in the oven for 45-50 mins or until the top is browned.
Allow to cool in the pan for at least an hour before slicing through and serving.
