Preheat the oven to 400 degrees Fahrenheit. Spray a rimmed baking sheet with cooking spray and set aside.
In a non stick skillet, combine BBQ sauce and chicken over medium heat. Bring to a simmer and cook for five minutes, allowing the BBQ sauce to thicken.
While the chicken and BBQ Sauce simmer, spread the chips over a rimmed baking sheet. When the chicken is done, scoop all of the chicken and BBQ sauce over the chips. Top with bacon, then cheese, and then red onions.
Bake for 15 to 20 minutes or until the cheese is fully melted.
Top with cilantro and pickled jalapeños and enjoy!
