👉 The term "non-cereal" is a slang term that refers to an object or item that does not belong in a cereal box. It can be used to describe any type of food, such as bread, pasta, rice, beans, etc., that is not typically served with a cereal. Non-cereal items are often found in smaller packages or on the side of a packaged food product, and they may not contain the same ingredients as traditional cereals.
