Steak Quesadillas are a great way to use leftover steak, and who doesn’t love steak? I had a ribeye leftover, didn’t want tacos, so I thought what better way to use the steak than in quesadillas that even Allen loves! The steaks were grilled, they were cooked to a perfect medium rare. I just toss the bite size pieces of steak in at the last minute after all my other ingredients have cooked and just heat it through because I don’t want to re-cook my steak. That would make it tough, definitely what I don’t want in a quesadilla that is hard to eat with big or tough fillings.
