If chicken is not grilled grill chicken and seson with season salt, cut into bite size pieces, set aside.
Roll out the pizza dough, lightly olive oil the crust, transfer to a "cornmealed" pizza stone or cookie sheet and prepare the ingredients for the base sauce in a small bowl. Spread the base sauce on the dough and put in a preheated 400 degree oven for 10 minutes. This prevents a soggy pizza dough.
While the dough is cooking grill onions and mushrooms on a cast iron grill (if you do not have a grill, do it in a skillet). Lightly salt to taste.
After the pizza dough has cooked for ten minutes, take it out and put a 3/4 of the grated cheeses on the pizza put all of the toppings on, putting the onions and mushrooms last. Top with the remaining 1/4 of cheese. Put in the oven for another 10-15 minutes.
While waiting for the pizza to cook, make the cilantro sauce topping, by blending ingredients in a food processor and placing it in a ziplock bag.
When pizza is done, cut the tip of the cilantro sauce bag with scissors and drizzle over the pizza.
