Speaking of Whole Foods, for those of you who are Celiac or just plain gluten-sensitive, Whole Foods has their own frozen pizza rounds which work just as well with this recipe. The secret is to thaw, spray the crust with either PAM Olive Oil spray or use your hands and lightly coat the crust with olive oil...all the way to the very edge. Put in 350 degree oven for ten minutes. Then remove, turn the oven to 400 degrees and proceed.
