Buffalo Chicken Quesadillas

1 store-bought rotisserie chicken, shredded (about 4 cups)
3/4 cup buffalo sauce
2 cups shredded Cheddar or Monterey jack cheese
12 flour tortillas
Nonstick cooking spray
Blue cheese dressing
Celery sticks

In a large bowl, combine chicken with sauce and stir until evenly coated. Add cheese and toss to combine. Evenly divide chicken mixture on six tortillas and top with remaining six tortillas.

Heat a large skillet over medium heat and coat with cooking spray. Cook quesadillas, one at a time, about 3 to 4 minutes per side, using a spatula to turn. Cut into quarters and serve with blue cheese dressing and celery sticks on the side.
