The classic chicken-and-macaroni soup recipe was first developed in the nineteenth century and is now one of the most popular comfort foods in the United States. The ingredients include blanched chicken, celery, carrots, bay leaf, water and salt. Bring the mixture to a boil and simmer for two hours. Season with salt and pepper and serve hot with garlic bread. To make this dish vegan, omit the cheese, add a can of coconut milk and eat it cold.
