Prepare the Dough – In a mixing bowl, combine flour, salt, and baking soda. Gradually add water and mix until a dough forms. Knead for 5-7 minutes until smooth, then cover and let rest for 20 minutes.
Incorporate Fillings – Roll out the dough and sprinkle with chopped green onions and grated cheese. Fold the dough over and knead gently to distribute the ingredients evenly.
Shape and Cook – Divide the dough into equal portions and roll each into a flat circle. Dust lightly with corn starch and flour. Heat a pan over medium heat and cook each flatbread for 2-3 minutes per side until golden brown.
Serve and Enjoy – Serve warm with butter, a yogurt dip, or as a side for soups and stews.
