This is my all time fav,
whole wheat dough
tomato's ( fresh)
some salt/pepper to taste
get a pizza stone, spread the dough out, you can use some cooking spray ( light of course) cut up the mushrooms, chicken, and anything else you wish to add.
Cook on grill for about 1/2 hour, 20 mins depending on how dark you like your pizza.
It is yummy and low in points....
