Sneaky Mommy Meatball Subs

These Sneaky Mommy Meatball Subs make for such a fun dinner! To make this a quick and easy weeknight dinner we use store-bought marinara but if you want to take it the extra step you can make your own. We recommend serving these subs with a side salad! Tip: Use the smaller side of your box grater for your vegetables if you can to best hide them!
