Originally called Cup-a-Soups there are now (in the UK) new strange flavours which you put in a mug, add boiling water and after stirring for a bit they're ready to go. The inspiration was to add grated cheese from the the grated cheese packet immediately after the first stirring session. It kind of dissolves and makes a glutinous liquid with some of the properties of the cheese and some of the soup base. Soups bearing some connection with cheese work best. Tomato soup + cheese is a bit icky.
