Start kneading the dough. In a deep bowl, mix kefir, sugar, salt and soda. Add melted butter, with it the flatbreads are softer and more delicate in taste. Gradually adding flour, knead a smooth, soft and elastic dough. Knead for 5-7 minutes, then roll the dough into a ball, place in a bowl and let it "rest" for 25-30 minutes, covering with a damp towel
Prepare the filling. Add 1-2 pinches of salt (if the cheese is not salty), chopped fresh herbs and 1-3 tbsp. of kefir to the grated cheese. Mix all the ingredients thoroughly, the kefir will moisten the mass and make it almost homogeneous.
Roll out the dough. Punch down the rested dough and divide it into 6 parts, roll each into a ball. Roll out the first part of the dough to a thickness of about 0.5-1 cm, adding flour to the work surface if necessary.
Form a flatbread for frying. Place some of the filling on the rolled out dough and pinch the edges of the dough around the filling to form a sort of “bag”. Sprinkle the place where the dough meets with a pinch of flour. Then turn it over and carefully smooth the flatbread to the desired thickness, pressing it with your palm against the surface of the table. If desired, you can roll the flatbread with a rolling pin to the desired diameter. Repeat this step with the remaining filling and dough.
Fry the flatbreads. Fry the prepared flatbreads on medium heat for 3-4 minutes on each side, in a dry frying pan, covered with a lid. After frying the flatbread on one side, turn it over and make a hole for the steam to escape, to do this, pierce the flatbreads in several places with a fork.
Place the pan-fried flatbreads on a plate and grease with butter. While you are frying the remaining pieces, you can cover the finished flatbreads with a plate or lid and wrap them in a towel to keep them warm.
