Preheat the oven: Before you start, preheat your oven to 180°C (350°F).
Roll out the dough: Place the fermented dough on the floor and divide it into small, equal pieces. Form each piece into a ball and form a small circle with your hand or rolling pin.
Add filling: Place a spoonful of vegetable and cheese filling in the center of each round. Roll up all the edges of the filling and press together to form a roll.
Prepare for baking: Place the filled rolls on a baking tray covered with baking paper. Cover them with a cloth and let them ferment for another 15-20 minutes.
Roll
Brush with egg yolk: In a small bowl, beat the egg yolk with olive oil. Brush the top of the roller with the mixture to create a shiny, golden finish.
Baking: Bake the rolls in the preheated oven for 20-25 minutes or until golden brown and cooked through.
