Preheat your oven to 400F.
Wash the Spaghetti Squashes, cut them in half, and remove the seeds. Drizzle the olive oil, season them with salt and pepper and let them bake in the oven for 40 minutes or until they are soft and cooked.
With a fork, scrap all the squash meat and let it cool for a few minutes. Place a clean towel in a bowl and transfer all that squash meat on top of that towel. Close the towel and twist it tight so you can squeeze all the extra water left in the squash. Make sure the squash is not too hot so you can handle the twisting. Place the squash meat in a bowl and with a potato smasher, smash your squash until smooth. Let it cool for 20 minutes.
Once your squash has cooled down, add your two beaten eggs, cheese, parsley and seasoning. Mix well.
Spray your pie dish with oil, cover it with baking sheet, and spray it again.
With a spoon, cover your pie dish with the squash mixture until you cover it completely. Make sure to flatten the mixture and that there's no hole. It should be even all across the bottom and the sides.
Bake it in the oven for no longer than 20 minutes until it has settled and the edges are starting to brown.
Remove from the oven and let it cool down while you prepare the filling.
