Preheat oven to 350 degrees. Heat olive oil in a frying pan on medium heat. Saute diced onion and jalapeño for 1 minute. Add minced garlic, and cook for another 2-3 minutes. Remove from heat.
In a large bowl, stir together shredded chicken, onion and jalapeño, cilantro, and shredded cheese until well mixed. Then add some of the barbecue sauce and mix well (start with a cup and add from there to your preference).
Spray cooking oil onto a cooking sheet, and place wraps fold-down onto the sheet. Bake in oven for 25-30 minutes, or until tortilla is crispy and the center is heated through. Enjoy!
Notes
If using smaller tortillas you will have more servings, so the total calories will be less.
