Preheat oven to 400°F (200°C).
Brush flatbreads with olive oil and place them on a baking sheet.
In a bowl, toss shredded chicken with buffalo sauce.
Spread the chicken evenly over the flatbreads.
Sprinkle mozzarella and crumbled blue cheese on top.
Bake for 10-12 minutes until the cheese melts and edges are crispy.
Drizzle with ranch or blue cheese dressing and garnish with green onions.
Slice and serve immediately.
