Pitas are a favorite lunchtime go-to for kids. This time, don't go for the preservative-packed variety. Make your own whole-wheat version and reap the benefits. Whether you fill, dip, or spread, the pita possiblities are endless. A pizza stone yields puffier bread. If you don't have one, use the back of a heavy jelly roll pan to bake these. After it has risen, you can keep the dough refrigerated for three days.
