I often have some dough left over when I use the breadmaker to make pizza dough, as with only two of us in the family, one medium-large pizza at a time is plenty.
So one of my mainstays for using up leftover dough is to simply roll it out very thin, spread some butter or margarine on it, sprinkle lightly with brown sugar and chopped walnuts, roll up, slice into bite sizes, bake and . . . yum!
