To make the quesadillas, sprinkle 1/4 cup cheese on the bottom of one flour tortilla. Top with 3 ounces of chicken, half of the diced red onion, jalapeño, pineapple, and bacon. Drizzle with half of the bbq sauce and sprinkle an additional 1/4 cup of cheese on top. Place another tortilla on top.

Heat a large skillet over medium high heat. Add quesadilla to the pan, letting cook on each side about 5 minutes, or until tortilla is crispy and cheese is melted. Use the remaining ingredients to make another quesadilla. Cut into triangles and serve warm.
