How to make
Dissolve the yeast in a bowl of lukewarm water, add salt, sugar, flour and knead until you get a smooth dough. Then tear small balls of dough and make buns.
Add the feta cheese and shape the bun into a ball. Place them in a greased pan together. Leave them to rise for about 30-40 minutes in a warm area.
Brush the top with melted butter and bake them in a moderate oven until golden. Bon appetit!
