@wikipedia suggests that a sandwich could be "any dish in which bread serves as a container or wrapper for another food type".
https://en.wikipedia.org/wiki/Sandwich#:~:text=any%20dish%20in%20which%20bread%20serves%20as%20a%20container%20or%20wrapper%20for%20another%20food%20typeIf so, then soup served in a "bread bowl" is literally a SOUP SANDWICH!
