Sift the flour. Dissolve the yeast with 1/2 cup cool water. To the yeast, add 1 tbsp sugar and 1 tbsp flour, stir and leave the mixture in a warm area until effervescent.
Pour the ready mixture into the flour, add the salt, 3 tbsp oil and 2 eggs. Stir and pour in a little more cool water until you can knead a smooth dough that doesn't stick to your hands.
Roll up the dough into a ball, cover it with foil and leave in a warm area to rise.
Divide up the ready dough into 3 balls. Roll out each ball into a sheet.
Smear each sheet with oil and sprinkle with feta cheese.
Put the sheets on top of one another and wrap it all up into a roll. Cut the roll into small pieces.
Turn the pieces with the cut sides facing up and arrange them in an oiled tray.
Bake at 374°F (190 °C) until ready.
