These make-ahead homemade uncrustables sandwiches are one of my most favorite kid-friendly lunch ideas for easy school lunches! They are always a hit with the littles, and they also work great for car trips, vacations, picnics, and other events!
Place individually wrapped sandwiches into a large gallon-size ziptop freezer bag. Label bag, and lay flat in the freezer to freezer sandwiches for several hours or overnight, until frozen solid. Be sure not to stack anything on top of your sandwiches until they are fully frozen. Then you can move them, stack them, or place them in a plastic food storage container for extra protection.
I just pull the sandwiches straight out of the freezer and put them in lunch boxes frozen. They are usually thawed by lunchtime.
If your kids will eat crusts, go ahead and spread your peanut butter and jam to the edges of your bread, then let your kids eat the crust pieces as a snack. If your kids will not eat crusts, then only spread a small circle, just slightly larger than your sandwich cutter, of peanut butter and jam on your bread - no sense wasting it on the uneaten edges! You can then use the crust pieces to make homemade breadcrumbs, croutons, use in meatloaf, feed to the birds/ducks, etc.
