Step-by-step photo did not do , since in principle I think that everything will be okay... Yogurt, vegetable oil, egg whites put in a container for the dough and stir. Add the grated cheese, flour and baking powder, dry paprika. Knead a soft dough. For comparison, say the Turks, the dough should be as "ear lobe". Roll into balls, spread with egg yolk , sprinkle with sesame seeds and bake in the oven for 15-20 minutes at temp. = 180°C. optionally, you can prepare muffins with olives.... A little finger pressure on the center of the ball, put the pickle, roll again into a ball. Bon appetit!!!
