Re:~ Sandwiches !!!
I'd probably try all of them, at least once.
Foodbme, Knife and forrk can still be a sandwich. Just think of the Kentucky Hot Brown or open faced hot covered turkey and roast beef sandwiches.
I must have missed something as i didn't see a soup/bread bowl sandwich in that list. I did see one that took the ingredients of French Onion Soup and made it into a grilled cheese sandwich. I did see something that looked similar to a bread bowl but it goes by the name of Pan Bagnat or Shooter's Sandwich. I think the NOLA Muffaletta may be "similar" in construction where the top of the bread is taken off, the insides are hollowed out and the ingredients are then layered inside, top put back on, wrapped up and then weighted down to allow the flavors to marry together before slicing.
