The quesadilla has had quite the journey in its existence. From its humble beginnings in Mexico, to now. It's available in just about every south of the border style restaurant in the world, from sit downs to drive thrus. I've come to notice that the mighty quesadilla is to adults what chicken nuggets and mac and cheese are to kids. Even the most picky eaters can always find culinary solace in the quesadilla, which does indeed make dining out a bit easier. Because again, you usually will always be able to find a quesadilla on a menu.
