Meanwhile, for the filling, peel onion and garlic and dice very finely.
Heat 1/2 tablespoon of olive oil in a small pan, fry the onion and garlic in it, remove from the pan and let it cool down. In the meantime, wash the herbs and pat them dry. Finely chop parsley and dill. Cut the chives into fine rolls. Mix onion and garlic mixture, herbs, remaining olive oil, egg and sour cream. Season with salt and pepper. Knead the dough again with floured hands and roll out to a rectangle (approx. 30x40 cm) on a lightly floured work surface. Spread with herb paste (leave a margin of 1-2 cm on each side). Roll up the dough from the narrow side. With the "seam" facing down, place on a baking tray lined with baking paper. Cover and leave to rise in a warm place for another 40 minutes.
