How to cook
Beat the eggs and add the oil. Stir the baking soda with the yoghurt until effervescent and add to the eggs.
Add the salt, then crumbled feta cheese. The flour comes last.
You need to obtain a mixture as thick as cake batter. Put it in a tray and bake at 356°F (180 °C) about 30 min.
Check to see if ready with a toothpick.
