In a medium to large mixing bowl, knead together all the listed ingredients, except the marinara.
Form your meatballs about the size of a large walnut or golfball and place them in the bottom of your crock.
Pour the marinara over the top of the meatballs.
Cook on low for approximately 3-4 hours (times will vary by slow cooker). When done, ladle the meatballs and sauce over some bread and enjoy!
