Origin: What am I, chopped liver?

Chopped (chicken) liver was a standard part of the post-Friday night services spread at my shul. It can be cooked well ahead, and can go with dairy, unlike beef liver. So the chopped liver in the expression is definitely chicken. I heard it in the late 1950s for sure, but I’m not surprised that much earlier cites have been given. It was an expression my grandparents were comfortable with.

Or we can goose up the history…
