ok you guys so here's the recipe, the ingredients you can adjust according to your taste, I never fully follow any recipe but it's 95% accurate, and there is 1 ingredient that I could not translate and i doubt that you would find in Europe, so instead i made so adjustment to the whole recipe, but it's still as good as the other one so hope you'd enjoy:

Ingredients:

250 g white flour
125 g butter
6 Eggs
1 small spoon of salt
1 bottle of sour cream (Crème fraiche)
1 Philadelphia cheese
¼ feta cheese
Around 10 leaves of spinach
¼ nutmeg

Preparation:

Place the flour and salt in a big bowl along the butter and mix with your hands until consistent, then add 1 egg and mix again, leave in the fridge to cool for 30 minutes. Then place it in a floured pan and cook for around 10 minutes in an oven on full heat. Chop the spinach leaves. Mix them with the sour cream and nutmeg. Place the remaining 5 eggs, the philli cheese and the feta cheese in a blender and mix well, then add the spinach, and mix everything. Spread above the dough and put in the oven for 30 minutes on medium heat. Serve hot and enjoy.
