This is good with any fillets of fish you fancy. I got tub gurnard (what?) from the fishmonger. Known as gallinella or lucerna in Italy, it’s a firm fish of the mullet family and is quite economical here.
I place a portion of fillets in the centre of a square of aluminium foil, add chopped tomato, black olives , capers and parsley and season with salt and pepper and a trickle of olive oil. I close the packages and cook them in the oven at 190°C for 15 minutes.
Couscous is a nice accompaniment (and quick!) but boiled new potato would be nice too.
