i like to take bluegill fillet them, sprinkle them with some salt, pepper, cajun seasoning, then squeeze a fair amount of lemon on the pieces and add a little butter in a tinfoil boat if that makes sense
throw it on the grill or the oven.. thats what we usually do with all our fish
im sure others will have more extravagant recipes.
I like to fry them in butter with some pepper, then get the meat off of the bones. Make sure I've got all the bone out and put it in an omelet. It's very good.
