While this may not be a combination you'd expect in a quesadilla, it's a winner with everyone in the household. I thinly cut the kale to make it easier to eat. As suggested by the Pioneer Woman, you can also toss the mixture with pasta and parmesean cheese, in a grilled cheese sandiwich, or make it into a soup.
