Dissolve 2 packages of active dry yeast and 1 T sugar in 1/2 c warm water. Let set 5 minutes. Add 1/3 c oil, then add 3 c All Purpose Flour (15 oz) and 3 c Bread Flour (12 3/4 oz) , 3 T sugar, 2 t salt and 1 1/2 c water. Mix in mixer with dough hook til dough leaves the sides. Put in a greased bowl, let double. Shape into sub rolls or hamburger or hot dog rolls. Let double and Bake at 400* for 20 minutes. I used about 9.5 oz for the 12 inch sub rolls. The recipe made 5 -12 inch sub rolls.
I cut each sub roll into 1/2 and freeze them. when I want a sub, I just thaw a while and make a sandwich.
