Slow Cooker Meatball Subs

Slow Cooker Meatball Subs | I don’t know about you, but I get cravings for slow cooker meals.  It could be anything as long as it’s in the slow cooker filling my house with delicious smells all day long.

One of my son’s favorite things to eat are Meatball Subs.  I think that boy could eat his weight in his favorite sammie if given the opportunity.  This recipe only takes four hours in the slow cooker and is delish on a toasted roll with a sprinkling (or a heap) of tart cheddar cheese.

    Making a batch of these right now. The sriracha + dijon mustard combination in the sauce seemed odd at first but now that I’ve tasted it I’m totally on board. Thanks 😉
