Step 2) Combine 1 cup flour, undissolved yeast, sugar and salt in a large bowl.  Add very warm water and oil; mix until well blended, about 1 minute.  Gradually add enough remaining flour to make a soft dough.  Dough should form a ball and will be slightly sticky.  Knead** on a floured surface, adding additional flour if necessary, until smooth and elastic, about 4 minutes.
