Anybody has any suggestions on how to not get whole wheat pizza crust hard and not dry??? I make my dough in a bread machine. I was so excited when my dough was rising and my pizza dough actually was smelling good. But when I start to stretch to put my toppings, it goes downhill from there. It keeps the shape of what I had when it's cooked and it looks really hard and dry. I don't understand what I am doing wrong. Any sugguestions??
