Warm the milk lukewarm. Mix milk, sugar and yeast. Let rest for about 25 minutes. Mix flour and 1/2 tsp. salt in a bowl. Add yeast milk, oil, yoghurt and egg and knead to a smooth, supple dough.
Let the dough rise for about 1 hour in a warm place, covered.
Lightly knead the dough and form into 6 balls of the same size. Leave to rest for a short time. Roll out into thin flat cakes on a floured work surface. Heat an uncoated pan. Fry the flat cakes for about 2 minutes on both sides.
