Preheat the oven to 400 degrees F. Line a rimmed baking sheet with parchment paper.
Combine the cheese, breadcrumbs, milk and egg in a large mixing bowl until well mixed. Add the chuck and pork and mix to combine, working gently to avoid overworking the meat. Sprinkle with the salt and pepper. Shape into small golf ball-size meatballs and place on the lined baking sheet.
Bake the meatballs until they are cooked through, about 15 minutes.
Meanwhile, bring the Classic Tomato Basil Sauce to a simmer. Transfer the meatballs to the tomato sauce and toss to coat, allowing them to simmer for another 5 minutes. Meatballs can be held in the sauce until ready to serve.
Cook the pasta according to package directions. Transfer the cooked pasta directly to the sauce, tossing to coat.
Serve the spaghetti and meatballs topped with grated Parmesan and fresh basil.
Cut an "X" in the bottom of each tomato and blanch in a large pot of boiling water 10 seconds. Immediately transfer the tomatoes with a slotted spoon to an ice bath to cool, then peel, seed and chop.
Cook the garlic in the oil in a small, heavy pot over medium heat, stirring occasionally until golden, 3 to 5 minutes. Add the tomatoes and red pepper flakes, season with salt and pepper, and add the fresh basil. Cover and simmer 1 hour, stirring occasionally.
