Good low-fat recipe for baked fish?

I’d like to serve baked fish for dinner tonight without using a lot of butterfat in the cooking. So many recipes for baked fish start with a half cup of butter. Butter, cream, sour cream, and other whole milk products are delicious, but I’d rather go light most of the time.

Can you recommend a good low-fat (and not too fussy or complicated) recipe for baked fish?
