Kefir pies with unsweetened filling fried in a frying pan

First, prepare the filling: mashed potatoes, fried mushrooms, overcooked minced meat and rice, fried cabbage with egg, thick jam… For our culinary recipe, any one will do. Now take a deep cup, pour kefir into it and drive an egg into it. Add salt, sweeten. Add flour, stirring constantly. Knead the dough until it stops sticking to your hands, now pour a little vegetable oil into it, mix again and cover with a towel for 10 minutes. When the dough settles, roll it out with a rolling pin into a thin layer and cut into identical circles 5-8 cm. in diameter. You can pinch off small pieces and form circles of dough with your hands. Put the filling in the center of each circle, pinch the edges tightly. Pour vegetable oil into a deep frying pan, heat it up and put the pies in it with a pinch down. The butter should cover the pies as much as possible. They are fried quickly, on both sides, until golden brown.
Everything, your food is ready, you can proudly tell that you did everything yourself, and did not use the semi-finished product.
