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 like these Slow Cooker Meatball Subs.

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.
