Pour the flour into a bowl and add the salt, oil, and enough water to obtain a soft and smooth dough. Divide the dough into 33 parts and let it rest covered with a cloth for 30 minutes.
In the meantime, wash the chard leaves, chop them finely, and cook them in boiling salted water. Once ready, drain and squeeze them, put them in a large bowl, and add the grated cheese and marjoram.
Drain the whey from the prescinseua and add the flour, oil, tablespoon of grated cheese, salt, and pepper.
Take 13 balls of dough and roll them out with a rolling pin very thinly, brush them with oil on both sides, and place them on top of each other in the pan.
Then spread the chard over top, drizzle with oil, and cover with prescinseua.
Use a spoon to create 12 divots, then crack an egg into each one and season with a pinch of salt and melted butter.
Roll out the remaining 20 sheets, brush each with oil, and gently layer them on the pie. When finished, roll up the edges to form the crust edge and brush the surface with oil.
