I don't cook fish much.
My options are either to do a main fishy dish, or to do "little bits" and let people pick.
Or go full veggie, but I get the impression that most animal-eaters are a little bit disappointed if they don't get some animal.
I'll have all evening the day before to prep or do stew/curry/etc, but not a lot of time on the day itself.
The people I've invited are lovely and will be happy no matter what, but I still felt like asking you clever people for some inspiration.
