In a large bowl, add the self-rising flour and yogurt. Use a spoon to mix together as well as you can, then switch to your clean hands. Mix with hands until ingredients are coming together and then turn out onto a clean surface to knead for about 5 minutes. If the dough is too dry (crumbly), add a tablespoon of yogurt. If it is too wet, add a tablespoon of self-rising flour. Once the dough is kneaded and smooth, roll it out into a circle. It should be about 1/2 inch thick.
