When you are stretching the dough, the whole grains and seeds may poke holes in it. Just patch them over and continue. Keep parbaked pizza shells on hand for quick weeknight meals. Roll the dough out into rounds and bake on a preheated pizza stone or baking sheet at 500 degrees F for 5 minutes. Cool, wrap the pizza shells well and freeze for up to 1 month. When ready to serve, add your favorite toppings to the frozen pizza shell and bake on a preheated pizza stone or baking sheet at 500 degrees F until hot.
