Baked Mackerel With Olives

Preparation:

Preparation: Rinse the mackerel after having cleaned and removed the innards, then drain them on absorbent kitchen paper. Crumble the breadcrumbs, add a little chopped parsley and the well-rinsed capers, a clove of garlic, the anchovies and the olives. Taste for salt and add a piece of chopped chilli. Soften the mixture by adding a little oil, then put a part inside the mackerel. Wash and cut the Treviso radicchio lengthwise, place it on the bottom of a greased baking dish, place the mackerel on it and spread the remaining breadcrumb mixture on top. Complete by placing the leftover garlic cloves cut into thin slices on the mackerel. Drizzle everything with a drizzle of extra-virgin olive oil and place the dish in the oven at 220 degrees for about 15 minutes. Serve hot.
