Mix together the chicken, mayonnaise, onion powder, red onion, bell pepper, and salt and pepper to taste.
Mix the 2 cheeses together in a bowl.
In a non-stick pan over medium heat, add half of the cheese mixture, forming a circle. Allow to melt and crisp on the bottom. Remove from the pan and repeat with the other half of the cheese to form your "tortillas".
Spoon the chicken mixture on top of one of the cheese "tortillas", then cover with the other cheese "tortilla" to form the quesadilla.
Slice and serve. Enjoy!
