Mozzarella Stuffed Meatballs

Spaghetti and meatballs are an absolute classic comfort food! There is no doubt about that! And in our home we love this classic dish.

These meatballs are stuffed with mozzarella cheese and cooked in a slow cooker making them delicious and easy on a busy schedule. I make these up the night before, fry the meatballs and refrigerate them overnight, so in the morning I can place them in the slow cooker and they are ready for our lunch! Serve these on top of spaghetti, with a fresh salad and garlic bread and you have a fabulous, comfort meal!

I have finished cooking these on stove in a pot of sauce if you are in more of a hurry to finishing the cooking process!
