Stir all of the ingredients together in a bowl until they start to come together. Use your hands to bring the dough together into a ball. Divide into two (or 4 if you'd prefer small flatbreads)
Roll each piece out flat on a floured board to a thickness of 2-3mm.
Place a large frying pan (or griddle pan) on a medium-high heat. Carefully add the flatbreads and cook for 2-3 mins until lightly brown and slightly puffed. Flip over and cook on the other side.
Notes
If the mixture looks very dry or very moist, adjust it slightly, as different flours can vary. Add either a little more yogurt, or a little more flour as necessary. You want the dough to hold together well, but not be too sticky.
