What is a novelty sandwich?

A novelty sandwich is a type of sandwich that is made with unusual or unexpected ingredients, or that is prepared in a unique or unusual way. Novelty sandwiches can be found in many cultures around the world, and they often reflect the local cuisine and culture. Some examples of novelty sandwiches include the Monte Cristo sandwich, which is a ham and cheese sandwich that is dipped in egg batter and fried, and the Reuben sandwich, which is a corned beef and sauerkraut sandwich that is topped with Swiss cheese and grilled. Novelty sandwiches can also be made with sweet ingredients, such as fruit or chocolate, or with savory ingredients, such as meat, cheese, or vegetables.
