1 14oz package of frozen meatballs
1 24 oz jar pasta sauce
Grinder rolls (or any long sandwich roll that you can cut open into a large hot dog bun)
In your crock pot, combine the meatballs and sauce, and cook on low for 4 hours. When ready to eat, cut your buns, but not all the way through, they should be like a hot dog bun. Place 4-5 meatballs in each bun and pour a little of the extra sauce over the top. Sprinkle a handful of mozzarella, and a light sprinkle of dried parsley over the top and place into a baking dish. Repeat this until you have enough sandwiches made for everyone.
Put the baking dish in the oven under the broiler for a few minutes, until the bun is lightly toasted and the cheese is completely melted, about three minutes. Serve with a side salad, and enjoy!
