RE: Future of the sandwhich
Wraps have been around for a while, and are just about everywhere. Same with Panini sandwiches; just another variation on grilled.
I have seen more vegetarian offerings, such as grilled Portobello mushrooms, although I know those aren’t new either.
I have noticed over the last year a lot of places serving mini-burgers or other mini sandwiches as appetizers…….whatever.
Not sure what else you can really do to a sandwich; seems like the best ones are made on good bread, with quality simple ingredients, well matched. How to improve upon that?
