In a mixing bowl, combine the flour and salt. Add the sourdough starter and water, mixing until a rough dough forms.

Knead the dough on a floured surface for about 5-10 minutes until smooth and elastic.

Add olive oil and knead for another minute until incorporated.

Cover the dough with a damp cloth and let it rest for 30 minutes.

Divide the dough into 8 equal pieces and shape each into a ball.

On a floured surface, roll each ball into a thin circle, about 8 inches in diameter.

Heat a cast iron skillet over medium-high heat. Cook each tortilla for about 1-2 minutes on each side, until lightly browned and cooked through.

Keep the cooked tortillas warm in a clean kitchen towel while you cook the remaining tortillas.
