The chances are, any meatball recipe you've ever seen involves some kind of cheese. And while it's standard to incorporate grated Parmesan cheese into the actual meat, there it becomes lost and unrecognizable. So what if you stuffed a block of cheese right into the middle of the meatball, and let it melt and get all gooey inside while it cooks? It certainly won't be lost, and you'll have a great dish to indulge in.
Frozen meatballs won't work here, so there is just a bit of work in assembling them beforehand. After that, though, they'll cook completely through in the slow cooker and become perfectly browned and delicious. The cheese will also stay intact until you cut the meatball open to reveal the surprise inside! If you want to serve them in sauce, just pour that over before setting the slow cooker, or you can choose to serve it on the side as a dip.

Pro tip: Want a really unique spin on this recipe? Use ground pork and stuff it with a small piece of crisp apple. It will all cook together for a delicious fall meal!
