Stir in the flour, salt, and olive oil. The dough will be thick and shaggy. Transfer the dough to a lightly floured surface and knead by hand for 3-4 minutes. The dough will come together into a smooth bowl. If dough is too sticky to work with, add additional flour just 1 tablespoon at a time. Transfer the dough ball to a large greased bowl and cover with plastic wrap. Place aside to rise.
