Place a large skillet that you can fit with a lid over very low heat.
In a small bowl whisk together the ingredients for the sauce.
Divide the sauce between three tortillas.
Working with one tortilla at a time, spray the skillet with a very small amount of cooking spray. Place the tortilla (that has been prepared with the sauce) in the skillet. Add about 2/3 cup of a cheese, 1/3 a cup of chicken and a little more cheese. Top with a second tortilla shell.
Let it cook for about two minutes or until the shell begins to turn golden brown. Cover while it is cooking. Flip it over, recover, and cook for another two minutes. Repeat with the other prepared tortillas.
Slice with a pizza cutter and enjoy.
I used light mayonnaise. It saves on the calories and doesn't change the taste.
