In a large mixing bowl, combine 2 pounds ground beef, 1 cup breadcrumbs, ½ cup grated Parmesan cheese, 2 teaspoons minced garlic, 1 teaspoon Italian seasoning, and salt and black pepper to taste. Mix gently with your hands until just combined.

Once browned, pour the 2 cans of crushed tomatoes over the Meatballs. Add 1 teaspoon Italian seasoning, salt and black pepper to taste, and ¼ cup chopped fresh parsley, if using.
