How to make
Beat the eggs. To them add the yoghurt, mixed beforehand with the baking soda.
Crumble the feta cheese and add it to the mixture. Finally add the flour and stir until the mixture absorbs it.
Using a wet spoon, place balls of the mixture in an oiled tray or onto baking paper.
Place a piece of cheese in the middle of each ball.
Bake in a preheated oven about 20 min.
