Begin by mashing the boiled potato until it's smooth.
In a mixing bowl, combine the mashed potato with the two eggs and half a cup of Greek yogurt.
Add a small amount of baking powder and a pinch of salt to the mixture.
Stir everything together until you achieve a smooth dough.
Shape the dough into small buns.
Brush the tops of the buns with egg yolk and sprinkle sesame seeds on top.
Bake the buns until they are cooked through.
