In food processor, combine flour, yeast, sugar, and salt. Pulse a few times to blend. With motor running, add warm water and 1 Tbsp olive oil. Continue processing until dough forms a ball and pulls away from sides of bowl. If too sticky, whirl in a couple more tablespoons of flour. Process for 1 more minute. Transfer to prepared bowl, turning dough in bowl to evenly coat with oil. Cover with clean towel and set aside in warm place to rise for about 45 minutes to 1 hour.
