Add the chicken and barbecue sauce to a mixing bowl and stir to coat the chicken in the sauce.
Heat a 12 inch skillet over medium heat. Add ½ tablespoon of butter to the skillet and let melt. Sprinkle a bit of kosher salt in the bottom of the skillet and lay a tortilla over the top. The salt will give a salty little bite to the outsides of the tortilla.
Arrange the chicken over half of the tortilla. Top with some crumbled bacon, ½ cup of shredded cheddar, some red onion, and a sprinkle of cilantro.
Fold the tortilla over the toppings to close and let cook for 2-3 minutes or until golden brown. Flip and continue cooking the other side.
Remove the skillet and place on a sheet pan in a warm oven to keep warm as you cook the remaining tortillas.
Cut the quesadillas into wedges and serve with extra barbecue sauce or ranch dressing for dipping.
Notes
We like a more peppery/spicy or tangy sauce vs. super sweet in this recipe. You can use whatever you personally enjoy.I like to cook my bacon in the air fryer. It's so easy and doesn't make a huge mess. You could also use turkey bacon or leave it out entirely if you're watching calories.
