A quick snack for the evening. Fatty fish is good for the brain, maybe it helps. The best thing is not to do to much to the fish, just a bit seasoning and a bit of flour. You can easily prepare them on a BBQ too.
I saw men in Portugal along the coast grill them on very small homemade BBQ boxes not bigger then a regular piece of paper, in front of their shops selling tires, carparts and so on.
The fish was cleaned and deboned from the fishmonger, the amount of work for this dish is very low. Serve it on top of some salad with lemon and olive oil dressing and you are good to go.
