Quesadillas are kind of the bomb. I mean you can choose so many different flavors (cheesesteak, jalapeno popper steak, chicken, bacon, & avocado, bbq chicken & pineapple, and copycat taco bell chicken) and they are typically very easy and quick to make. What I love about this particular quesadilla recipe is that the flank steak goes into the crockpot and by dinnertime, you get this ridiculously delicious filling for the quesadillas. Unbelievably good!
