Always as a part of the kilo of herrings I’ve bought, those are inspired by the much more famous Sarde a beccafico, a typical Sicilian dish.
The problem with this recipe is that I haven’t measured the ingredients, but just followed the moment…

4 herring fillets
Breadcrumbs
Fine grain couscous
Raisins
Pinenuts
Cappers
Dill
Extra virgin olive oil
Garlic

Heat the oil and stir fry the minced garlic. Add the rest of the ingredients and cook for about 10 minutes, adding some spoonful of hot water.
Lay each fillet and spread some of the breadcrumb mixture on it. Roll it and close it with a toothpick. Cook it in a pan with some oil for 10-15 minutes.
