Meatball Sub Casserole

Are you ready for some pure deliciousness?  I had this casserole over the weekend and I fell in love!  I scoured the internet and came up with my own concoction that is closest to what I had this weekend.  If you love the traditional meatball sub, you will love this recipe!  My kids have a hard time eating meatball subs so this is the next best thing!

Check out this yummy goodness!
