Flatbread is part of the culinary traditions of countries in the Maghreb and Mediterranean regions. They're perfect for serving with grilled meats or veggies, or to dip in sauces and spreads. All that's required is to mix the ingredients in a bowl and knead for a few minutes. Shape them into discs and cook them directly on the grill. The bread is soft and puffy thanks to the addition of yogurt, and is sure to satisfy.
