Origins of "What am I - chopped chicken liver?"

Factual Questions
1

I know chopped chicken liver is basically pâte, but I’m not clear what that has to do with the expression “what am I - chopped chicken liver?” to denote that you’ve been ignored. (Usually after other people have been acknowledged and you should have been too).

If someone could explain to me why “to be overlooked” relates to chopped chicken liver, I would appreciate that.

But the main question I have is, does anyone know from where the expression originates? Perhaps a famous person, or a certain country, or a certain profession ie. the culinary profession?

I believe it’s a (possibly NYC-specific) Jewish expression which refers to chopped liver being served as a mere side dish.

The expression is currently traced to the 1940’s. Almost certainly US. And if a Jewish comedian first used it, it wouldn’t be surprising.

The expression seems to have been, at that time, “and that ain’t chopped liver” or some variant of that. Meaning, it isn’t cheap.

I think that chopped liver in a Deli in the 1940’s or earlier, would certainly have been cheaper than the pastrami, corned beef, etc.

And, to finish, taking the expression from “that ain’t chopped liver” to “what am I, chopped liver?” is simply modifying it to say “what am I–insignificant?”

Okay, but take some friendly advice and leave the “chicken” out of it. I’ve never before seen or heard it with that extra word in the phrase, and now I can see why. It’s unnecessary, and it makes it cumbersome, destroying its rhythm and punch.

Well, I didn’t know it was a side dish. That explains it rather well. Thanks for the replies, folks. (And I swear I searched the archive. Humph).

(Gary T, I’ve only ever heard it with chicken in there. Blame my parents, I guess. Or the Mid-West).

A minion, you think I am? All by myself? I’d need nine other … umm…

Chopped liver with minions? No, no, no. Chopped liver with onions!
