Sunnies? Right into a good ol' frypan with some oil, or butter, if you're not picky, and salt & pepper.
I wouldn't bake them, that can leave small bones noticeable that would otherwise cook up. Could cause some "newbs" to get upset. I would do fish cakes. Make them ahead of time and freeze, then just lay them on a cookie sheet to thaw for a few minutes and fry.
fried gill fillets are the perfect size for a taco shell, add a little guacamole, and some slaw... you'll be good to go
