Preheat your oven to 425°F.
In a medium-sized mixing bowl, toss the precooked chicken with ½ cup of BBQ sauce, setting aside the remaining ¼ cup.
Spread the reserved ¼ cup of BBQ sauce evenly over the two flatbreads, going right to the edges if you like.
Top each flatbread with an even layer of the shredded BBQ chicken.
Sprinkle 1 cup of shredded cheese over each flatbread.
Place the pizzas directly on the racks of your preheated oven for a crispier crust, or use a baking sheet if preferred.
Bake for 8-12 minutes, or until the flatbreads are crispy on the bottom and the cheese is fully melted.
Once done, remove the flatbreads from the oven and let them rest for about 5 minutes before slicing and serving. Enjoy!
