In a large bowl, add the flour, yogurt, olive oil and salt.
Stir to combine until it comes together, then transfer to a floured board.
Knead for a few minutes until you get a springy dough.
Heat a large griddle pan or frying pan to medium.
Divide the dough into 4, then roll out the first flatbread.
Pop it on the griddle pan and allow to cook and char a little on that side, then flip to cook to on the other side.
Top with olive oil, za'atar and sea salt flakes.
Repeat.
