Preheat your barbecue, creating an area of hot coals and a cooler area with no coals on the opposite side. (Get an adult to help you with this bit.)Mix the flour with a little pinch of sea salt in a large bowl, add the yoghurt and the olive oil, and mix together with your hands until you have a smooth dough.Cut the dough in half, then half again and roughly roll out each piece into a long sausage shape, using a little flour if the dough feels sticky. Wrap the dough tightly around and around the end of a (clean!) stick, until it looks like a little helter skelter. Pinch the end of the dough together so it’s nice and secure.Hold the stick about 15 to 20cm over the hot coals, toasting the dough as you would a marshmallow. Cook the bread, turning every now and then, until golden on all sides. (This should take about 5 to 10 minutes.)Leave the bread to cool slightly, then break it off the stick and brush with a little olive oil or butter – it’s especially good for dunking in Buddy’s smoky beans!
