Preheat the oven to 425 degrees F.
Place flatbreads on a parchment paper lined sheet pan and brush the edges lightly with olive oil.
Bake the flatbreads for 5 minutes until warmed and just starting to crisp.
Remove from the oven and spread the buffalo sauce evenly over both flatbreads. Sprinkle diced chicken and mozzarella cheese on top. Drizzle the blue cheese on top.
Bake for 12-15 minutes until edges are slightly browned. To brown the tops, place under the broiler on high for the last 1-2 minutes.
Remove from oven. Sprinkle with sliced green onions and additional buffalo sauce and blue cheese if desired.
