In a food processor, combine the flour, salt, and olive oil. Pulse about 10 times until the mixture is gravelly.
With the processor running, slowly add the cool water through the top until the dough begins to form a clump.
Turn the dough out onto a lightly floured surface and knead for about 3 minutes until it's elastic and can withstand a firm tug without tearing.
Divide the dough into 6 equal pieces, roughly 80-90 grams each, and roll them into balls. Cover with a damp towel and let rest for 15 minutes.
