The area in a quesadilla between the edge of the tortilla and the location of the cheese on the inside. Large dead zones are found when someone who is inexperienced prepares a quesadilla and only puts cheese in the middle of the tortilla, incorrectly assuming that the cheese will disperse while melting.
"How was your quesadilla?"
"Not very good, dead zone was huge and it felt like i was eating tree bark."
