Besides BLT and BEST, are there any sandwiches that are known by their initials?

Peanut butter and jelly (or jam) . . . thanks, I'd not heard it called that before. What sort of jam would you use, Jai? Strawberry, raspberry, apricot or other?

PB&J was the only sandwich I could think of that is sometimes referred to by initials but it is not something I have ever liked, even as a kid. I think it’s the texture that puts me off, too smooshy and mushy. I don’t like jam on toast though and I like strawberry for that :) 

I had to look it up. Interesting . . . I'd never thought of the idea of using ground beef in a sandwich before.

Really? What do you think a hamburger on a bun is?

Don’t start. 

Huh? All I said is that a hamburger on a bun is ground beef in a sandwich. What part of that is wrong?
