Place the sourdough starter, strong white bread flour, sea salt and olive oil into a bowl. Mix until a soft dough forms.
Tip onto a lightly floured work surface and knead briefly until smooth.
Divide the dough into equal portions, then roll each piece into a thin round.
Heat a pan over a medium-high heat.
Cook the flatbreads for 1–2 minutes on each side, until lightly coloured with charred spots and cooked through.
Serve warm.
