Mix the egg, flour, yoghurt, baking powder, Tat Diced Tomatoes, coriander, salt, and black pepper in a deep bowl using a mixer. Then add chopped fresh mint, parsley, dill, chopped onion stalks, and grated feta cheese, and mix with a wooden spoon. Take a desired amount of dough and roll it (if the dough sticks to the hand, add flour). Place the bread on a greased tray. Draw three horizontal lines on each piece with a knife and apply egg yolks with a brush. Finally, sprinkle black cumin seeds on the bread and bake them in the oven heated to 185 degrees until they turn golden brown. Serve hot.
