Make every night Mexican night with this savory, and a wee bit spicy, quesadilla! By using cilantro, black beans, avocado and a touch of jalapenos, this dish has all the usual suspects. Serve it up with some fresh greens, a bean salad or slice it up into bite-sized slices and serve as an appetizer. Make this dish even faster by using up leftover chicken from the night before and listening to salsa music – cooking has never sounded so good!
