In a mixer, add flour, salt, sugar and yeast. Mix at medium speed and add the olive oil and water. Mix until well blended. The dough should form a ball when done. Add more flour if it seems too sticky; or more water, 1 tbsp at a time, if too dry.
Lower the speed of the mixer, (2 or less for a Kitchen Aid), and kneed the dough for 20 minutes.
The dough should form a smooth, slightly sticky ball when done.
