A sandwich that contains all aspects of a large dinner.
For instance: With a roast/Sunday dinner, one may put mashed potato, carrots, roast potato, chicken (or whatever meat you have) and possibly a Yorkshire pudding.
The kinds of Grandwiches are endless.
Bill: Man, I just chowed down on the most epic Grandwich!
Bob: ... Grandwich?
Bill: Yeah! The sandwich of all aspects; The Grandwich! It is legion, it does not forgive, it does not forget. Expect it.
