Combine flour, baking powder, salt, semolina flour and whisk to combine. Stir in the Greek yogurt and mix to form a soft, pliable dough. Add some water, if the dough seems too thick. Cover and set aside for 30 minutes.
Divide the dough into 8 equal pieces. Roll each piece into a round or oblong shape.
Heat a griddle on medium high heat and cook the flatbreads until golden brown spots form, about 2 minutes each side. Brush with oil while cooking.
Keep warm until ready to serve. Enjoy with your favorite dip or curry.
