Lay fish (best with whole fish) on aluminum foil. And at the same time preheat oven at 180-200 degree.
Season fish with pepper, salt, herbs and lemon juice. Leave to rest.
Stir fry onions with olive oil.
Pour the hot oil with onions over season-ed fish.
Personal preference, I like to throw in some halved cherry tomatoeS on the fish – to give some sweet/sour flavour.
Wrap the fish up in the aluminum foil and then send it to the oven. (I did not use foil because I’ve got my own baking gear)
