In a large, lined slow cooker, stir together the tomatoes, EVOO, garlic, 1 tsp. salt, 1/2 tsp. pepper and the crushed red pepper. Cover and cook on high heat for 2 hours.
Meanwhile, in a large bowl, using your hands, gently knead together the beef, half the parsley, the breadcrumbs, cheese, eggs, 1 tsp. salt and 1/2 tsp. black pepper. Shape into about 72 balls (about 1-inch diameter).
Place the meatballs in the cooker and stir to coat with the sauce. Cover and cook on high heat until the meatballs are no longer pink inside, about 2 hours. Gently turn the meatballs in the sauce every 30 minutes.
Using a shallow spoon, degrease the surface of the sauce. Stir in the remaining parsley. Serve the meatballs with the bread.
