Ah, potluck is a term I'm familiar with.

You can make a casserole out of almost anything but the base is some kind of meat, a variety of vegetables all on one pan with enough liquor or whatever type to make a sauce, cooked fairly slowly in an oven.

I've used soup, not just mushroom but minestrone and chicken as well, but I've never put eggs in a casserole.

This is the sort of thing one needs a Brit/US picker for.
