Preheat the oven to 450.
In a medium bowl, combine the PB2, soy sauce, water, garlic powder, black pepper, sriracha, brown sugar and sesame oil and whisk together to combine.
Spread the peanut sauce evenly across the top surface of the pizza crust, leaving at least a ½ inch edge around the outside. Sprinkle the chopped chicken pieces and scallions over the top, followed by the mozzarella cheese. Finish the pizza by sprinkling the carrots and bean sprouts over the top.
Place pizza on a foil covered baking sheet, a pizza stone (my preference) or straight onto the oven rack (depending on how you like your crust) and bake for 8-10 minutes. Sprinkle chopped cilantro over the top before serving.
