Add the flour and salt to a large bowl–mix well.
Mix the yeast, sugar, olive oil with the lukewarm water and leave for a minute.
Create a hole in the middle of the flour and gradually add the liquid until you have a dough. Tip the dough onto a well floured chopping board. Knead for a few minutes until the dough is springy. The dough is quite wet, so keep adding more flour if needed.
Transfer back to the bowl and cover with a damp cloth for about a hr. The dough should have doubled in size.
Transfer back onto the floured chopping board and knead again to knock back.
Heat a griddle pan or frying pan. Divide the dough into 4, add a little more flour if needed, then roll out into flatbreads.
Add the dough to the pan and heat on each side for a few minutes until the flatbread is fluffy, a little charred and cooked through. Repeat.
