Italian Meat and Tomato Sauce is a classic Italian dish that is often served over pasta. The two most popular versions of this dish are Ragu, which is a slow-cooked sauce made with ground beef, tomatoes, onions, celery, carrots, and herbs, and Bolognese, which is a meat-based sauce made with ground beef, pork, and/or veal, tomatoes, onions, celery, carrots, and herbs. Both sauces are typically served over spaghetti or other types of pasta.
