Preheat the oven to 375 degrees.
Prepare the flatbread and place on a baking pan lined with foil.
In a medium bowl, whisk together the peanut butter and water until smooth. Add in the remaining peanut butter sauce ingredients and combine. Spread a thick layer of the sauce over the flatbread, saving ¼ aside for drizzling at the end.
Spread a layer of the sliced chicken across the top of the peanut sauce. Pile on the red bell pepper, carrot shreds, green onions, and mozzarella cheese.
Bake the flatbread for 8-10 minutes until the cheese is melted. Drizzle the remaining peanut sauce on top of the pizza. Sprinkle on fresh cilantro, crushed peanuts and a squeeze of lime.
