Preheat oven to 375.  Lightly grease a cookie sheet. Roll frozen bread dough out into a rectangle.  Arrange pepperoni and cheese onto the dough.  Roll up like a jelly roll and pinch seam to seal.  Place seam side down, on the prepared cookie sheet.  Score the top where you would like to slice it.  Brush with hot water that you have added a little salt to.

Bake for about 40 minutes until golden brown.
