Preheat oven to 350 degrees.
Place 1 flatbread onto a non-stick baking sheet.
Bake flatbread for 10 minutes to crisp up. (Optional: flip over half way through)
While that is cooking: if you haven't yet, sliced your onions & shred chicken.
Add 1 tbsp buffalo sauce to shredded chicken & mix until chicken is well coated. Set everything aside until it is time to assemble.
Remove flatbread from oven.
Spread minced garlic evenly across flatbread.
Add buffalo coated chicken, mozzarella & red onions.
Finally, top with green onions.
Place flatbread back into oven for 5-10 minutes until your cheese is completely melted.
Remove from oven, cut into thick pieces, serve & enjoy!
