Some dishes will never win a beauty contest. These slow cooker Sloppy Joe beef quesadillas may not take the swimsuit competition, but oh, they are good. And, like real Sloppy Joes, they're sufficiently messy to eat. You can cook the meat ahead of time, in your slow cooker, and freeze it in portions to fill quesadillas, tacos or burritos, whenever you want them. Add something green -- chopped avocado, lettuce, cilantro leaves -- or serve them with nothing more than melted cheese, and a bit of salsa on top. Summer should be just that easy.
