For dough: combine 1 1/2 cups flour, yeast and salt in large mixing bowl. Add water and 2 tablespoons oil. Beat with an electric mixer on low speed 30 seconds or until combined. Beat on high speed 3 minutes. Stir in as much of the remaining flour as possible. Turn dough onto lightly floured surface. Knead in enough remaining flour until dough is smooth and elastic, about 7 minutes. Place dough in lightly oiled bowl; turn to oil top. Cover; let rise in warm place until doubled in size, about 40 to 50 minutes.
