Sift the flour into a large bowl. Dissolve the baking soda in the yogurt and add it to the flour. Add the egg.
Gradually add the remaining ingredients - salt, sugar, yeast (or baking powder), and oil - and knead until a soft dough forms.
Cover the dough and let it rise for about 30 minutes.
Divide the dough into small portions and shape each into a thin flatbread using your hands.
Prepare the garlic butter by melting the butter slightly and mixing it with the pressed garlic and chopped parsley. Brush the flatbreads with the aromatic mixture.
Cook the flatbreads quickly on a grill, in a pan, or bake in the oven until lightly golden and cooked through.
