Sloppy joes are a kid favorite that don't get as much credit in the adult world as they should. Of course, you can help remedy that by making a batch for dinner and another for the freezer. Your kids will applaud the promise of future joes, and you'll also look forward to another messy meal.
Just make a big batch of sloppy joe meat, eat what you want, and let the rest cool. Place the meat into one or more freezer-safe containers, leaving a half-inch or so of room at the top for it to expand during the freezing process. It'll keep for two to three months in the freezer.
