Add ONLY 4 eggs to the mixture. We will use the 5th one to brush the pie on top.
Mix everything well. Set aside.
In the meantime, preheat the oven to 350F.
Cover the bottom of a baking tray with parchment paper.
Open one sheet of filo pastry and brush with some oil (pour a few tablespoons of oil into a cup and use a pastry brush).
Place another sheet on top and brush with oil again.
Repeat this process until you have 5 sheets, one on top of the other.
Place half of the filling mixture along with one of the phyllo's narrower edges, but stopping a couple of inches (5cm) short of the edge at each end.
Fold in the few inches (5cm) on each side of the phyllo all the way along (to hold in the filling), and then roll the whole thing up into a roll. Place the roll on a baking tray.
Repeat the same process with the other roll. Lastly, beat the egg and then brush the top of the pie rolls.
Bake at 350F for about 40-45 min or until golden brown.
