Stir together 2 cups flour and the yeast. In a separate bowl, heat water, oil, sugar, and salt to lukewarm in the microwave. Add all at once to flour mixture, and beat until smooth, about 2 minutes.
Mix in enough of remaining flour to make a soft dough (I use all remaining 3 cups). Mix well. Dust a flat surface with flour, turn dough out onto floured surface, and let rest under bowl for 10 minutes.
Shape dough into rolls, etc. and please onto greased cookie sheet to rise until double in size. (For me, this step takes about 20-30 minutes).
Bake in a preheated 400 degree F oven for 12-15 minutes or until golden brown.
If I am making hamburger buns, I just really flatten out the ball of dough before the last rising on the cookie sheet.
