In the meantime, prepare your Peynirli Pide filling by grating mozzarella and cheddar cheeses. Crumble feta and set aside.
In a non-stick pan add olive oil and over medium heat saute minced garlic and onions for 5-6 minutes until tender.
Place the risen dough on a lightly floured surface. Knead the dough for a minute then divide the dough into two pieces and roll into two balls.
On a lightly floured surface, roll the dough balls into 2 oval shapes of 20 cm x 40 cm with ½ cm thickness.
Line a large baking sheet with parchment paper and place the 2 oval flat dough pieces on the tray.
Use a spoon to spread the onion and garlic mixture onto the surface of both slices of dough.
Sprinkle the feta, cheddar and mozzarella cheese over onion mixture, leaving 2 cm at the edges as a border with no filling.
Fold in the sides to act as crust to keep the filling intact. Squeeze the oval dough at each end to make it pointy.
Top each pide with slices of cured sausage like chorizo.
Beat an egg in a small bowl and mix it with a few drips of olive oil. Brush the edges of dough with the egg mixture.
Bake for 25-30 minutes, until the Turkish Pide are golden brown and crispy at the edges.
Once cool, cut into slices and serve.
