Preheat oven to 450 degrees then line a baking sheet (may need 2) with parchment paper and set aside.
Combine Peanut Sauce ingredients in a bowl then whisk until smooth. May need to microwave for 10-15 seconds to help warm the peanut butter.
Heat oil in a medium-sized skillet over medium-high heat. Add ground chicken, 2 Tablespoons Peanut Sauce, salt, and pepper then saute until chicken is cooked through. Set aside to cool slightly.
Spread 2 Tablespoons Peanut Sauce on each flatbread then top with a quarter of the cooked chicken, cheese, chopped broccoli, and green onions. Bake pizzas for 7-9 minutes or until cheese is melted and bubbly then cut into quarters and top with chopped mango, peanuts, and cilantro.
Notes
Serve with extra peanut sauce for dipping crust into!
