In a large bowl mix all ingredients for the meatballs in order together, do not add the sauce, then form balls. I use an ice cream scoop to form the meatballs as it's about the size you will want them to be.
Next spray your slow cooker with a good coat of non stick spray and place the meatballs in the slow cooker.
Pour the cup of pasta sauce over them and let them cook on low 6-8 hours.
When time for dinner, heat up the rolls according to the package.
These rolls are similar to having a muffin top, when they are cooked, cut the muffin top off. Then, place one meatball on the bottom portion of the roll top with a spoonful of marinara and cheese. Place the muffin top back on the sandwich and serve!
