Black Bean Quesadillas

From the backlog: 5/16

J. and I worked all afternoon into evening, and just as we were deciding to run out to the grocery store, a downpour started. So I fashioned these black bean and roasted red pepper quesadillas out of the ingredients I could scavenge from my refrigerator - black beans, roasted red peppers, red onion, cheddar cheese, whole wheat tortillas, and cilantro.
