Brush a 25 cm pie-dish with olive oil.
Heat the oven to 180ºC (350ºF).
Roll out one of the two heavier balls of dough on a floured surface until it is so thin that you can almost see through it.
Drape it over the pie-dish and push it down gently with your fingers until it lies flat against the dish. Brush the dough with oil.
Roll out the second heavier ball of dough in the same way, then drape it over the pie dish and gently push it down until it lies flat against the first round of dough.
Add the spinach mixture and flatten it gently with a spoon.
Add the ricotta mixture and smooth it out over the top of the spinach.
Wet a tablespoon and make five indentations in the ricotta and regular intervals.
Break the last five eggs, one at a time, and gently drop them into the indentations.
Sprinkle grated Parmesan Cheese over the top of the eggs.
Roll out the third ball of dough thinly and drape it over the top of the pie. Brush it with olive oil.
Roll out the last ball of dough and drape it over the top of the third circle of dough.
Cut the excess dough off from around the edges of the pie dish.
Carefully roll the edges up and press them on to the surface of the pie.
Brush the top with oil, and bake for 50 - 55 minutes.
