How to make
Add the eggs, cheese, oil and yogurt, in which you've dissolved the baking soda beforehand, to the flour. Knead a dough and divide it into 15 balls.
Out of each ball, make a roll with a hole in the middle and put a knob of butter and feta cheese in it. Arrange the buns in a greased oven dish and bake them in a moderately hot oven until the loaf gets a golden tan and rises.
