Prepare the batter for the chops. Grate the cheese on a fine grater. Put the grated cheese, sour cream and eggs in a bowl. Add pepper, salt and flour, mix well. Take sour cream with at least 20% fat. The batter should be thick and not spread from the meat.
Prepare the chicken fillet. Cut the breast into slices and beat gently with a kitchen hammer. Grease each chop with batter. Place in a preheated frying pan with vegetable oil. Fry for 7-10 minutes over moderate heat. Spread the remaining batter evenly over the chops. Turn the chops over and fry for another 7-10 minutes.
