Place flour and salt in the bowl of a food processor and pulse to combine. Add 2 1/2 cups lukewarm water, yeast, sugar, and olive oil. Process until a dough has formed.
Dust a large bowl with flour and transfer dough in bowl. Sprinkle flour on top of dough and cover with a damp towel. Let stand in a warm place until doubled in size, about 1 hour.
Punch down dough and turn out onto a lightly floured work surface. Use immediately, or wrap dough in plastic wrap and keep refrigerated until ready to use.
