How to make
Dissolve the yeast in a bowl and add the sugar and warm water. Sift the flour and in the middle put the dissolved yeast, yoghurt, eggs + the egg white, salt and finally the oil, gradually kneading into a smooth dough. Leave it to rise well.
Meanwhile, heat a little oil in a pot and fry the finely chopped leeks, grated carrot, finely chopped mushrooms and add the minced meat. Stir until the mince fries and add 1 tablespoon of ketchup and mustard. Finally, season it with salt, black pepper and a little cumin and savory.
Divide the dough into 12 balls. Roll out each one, smear it with a little chutney in the middle and put the filling there. Bring the ends together and form slightly oblong rolls.
Arrange the buns on a tray with baking paper with some space between them. Leave them to rise for an hour. Brush them with beaten egg yolk and with a tablespoon of water and a tablespoon of oil.
Bake the stuffed bread in a preheated 360°F (180 °C) oven until they get a nice tan.
