" To make sauce: In a large saucepan, heat oil over medium heat. Add onion, carrots, celery and garlic. Cook, stirring frequently, until vegetables begin caramelizing, about 12 minutes. Turn heat to low; cook until very soft, 10-15 minutes. Raise heat to medium; add tomatoes. Bring to a simmer and partially cover. Cook 30-40 minutes, stirring occasionally. Season with salt and pepper. Preheat oven to 450 degrees. Bring a large pot of water to a boil. Cook spaghetti according to package directions, subtracting several minutes off cooking time so it comes out very al dente. Drain well; add to sauce. Add parsley and red pepper flakes; toss to combine. Transfer to a 2-quart baking dish. Spread level. Sprinkle with cheese and bread crumbs. Drizzle with olive oil. Bake until top is browning and sauce is bubbling, about 15 minutes. Serve immediately."^^<http://www.w3.org/2001/XMLSchema#string>
