To thaw the frozen bread dough place the dough loaf in the fridge (on a plate and covered) for several hours. I put mine in the fridge to thaw the morning of and then I make the rolls the same night and leave in the fridge so they're ready to bake the next morning. If you're unsure about thawing then follow the directions that are on the package. When you are ready to roll out your dough it helps if you let the dough rest and get a little warmer before you roll it out. Aim to roll the dough as big as your 9x13 pan.
