Toss "chicken" with a few tablespoons of the sauce and set aside.
Preheat oven with pizza stone to 500 degrees.***
Stretch your dough as large as you can to get a thin crust. You may need to shape your pizza into the shape of your stone to create a large pizza that fits.
Prick dough with a fork to prevent air bubbles, and lay stretched dough on parchment paper and place in oven.
Cook dough until lightly browned on bottom, about 5 minutes.
Remove dough from oven and turn over, so that the bottom of the dough is now the top.
Spoon remaining buffalo sauce on dough.
Sprinkle onions and chicken evenly across the dough and season lightly with salt and pepper.
Top with mozzarella and blue cheese and place back in oven (still on parchment paper).
Cook until cheese is melted and bubbling.
Remove pizza from oven, sprinkle with celery, celery leaves, and cilantro and serve.
