In a medium bowl, season the chicken breasts with salt, pepper, and olive oil. Drizzle half of the BBQ sauce over the chicken and toss to coat.
Place the seasoned chicken breasts on a sheet pan and bake in the preheated oven for about 20-25 minutes, or until fully cooked and internal temperature reaches 165°F (75°C).
While the chicken is baking, prepare the vegetables. In a separate bowl, combine sliced red onion, bell peppers, corn, and the remaining BBQ sauce. Toss well to coat.
Once the chicken is cooked, remove it from the oven and let it cool for a couple of minutes. Shred the chicken using two forks.
On the same sheet pan, lay out the flatbreads or naan. Evenly distribute the shredded chicken on top of each flatbread.
Next, evenly sprinkle the veggie mixture over the chicken.
Finally, top each flatbread with shredded mozzarella cheese.
Return the sheet pan to the oven and bake for an additional 10-15 minutes, until the cheese is bubbly and golden.
Once done, remove from the oven and allow to cool for a couple of minutes. Garnish with fresh cilantro or parsley before slicing into wedges.
