In a large bowl, combine all of the ingredients and mix with your hands.
Spray bottom of slow cooker with a non-stick cooking spray (I use PAM)
Form the meat mixture into 1-inch balls and place them in the bottom of the slow cooker.
Cook on LOW for 4-6 hours.
Notes
Note: Cooking time may differ between slow cookers. Mine is relatively new and seems to cook in less time. It was able to cook the meatballs in about 4 hours.
