In a deep bowl, grate the zucchini on a fine grater. If the zucchini is young, then I do not remove the skin. Add egg, salt, yogurt and flour. Mix everything well. The dough is ready.
Put about 3 tablespoons of zucchini dough on a preheated frying pan with vegetable oil and spread evenly over the surface of the pan. After a minute, put a spoonful of chicken and onion on one side of the pancake.
