If pizza is a sandwich (open-faced) and chili is stew then cereal is definitely soup.
prove me wrong
Take a tomato, chop it up. Add a tablespoon of sugar and mix them together in a bowl. Refrigerate for an hour (or more). Enjoy your fruity snack and thank me later.
but this is soup
says so on the package and it's drier than your Grandmother's hoohoo
soup, from Latin, suppa is a liquid stock or broth based dish meant to be sopped (also roots from suppa, sup, supper) with bread. Stocks and broths may be meat or vegetable based. Cream based soups always have a thickener, such as starches, pureed vegetables. Cereal, or cold cereal (with milk), is a classification of dishes known as cereal, because it is comprised of cereal grains. It doesn't matter if it is served with milk, or not as oatmeal often is not. Cereal grains added to a stock or broth is still soup. If you were to have claimed a thick soup was a stew, you would have had an argument.
