Storing Leftovers

Remove meatballs and sauce from your slow cooker and transfer into an airtight container and refrigerate. They are good for up to 4 days. 

I don’t recommend making the sandwiches and then storing them. The sauce will make the hoagie rolls soggy. 

Also, you can change things up. Instead of making meatballs subs again you can make spaghetti.
