We need one Mackerel per person, lemon juice, a bunch of parsley, olive oil, salt.
Clean the mackerel, wash it, dry it with a napkin and salt it. In a bowl, mix olive oil and finely chopped parsley.
Coat the mackerel inside and out and let it stand for a while.
Meanwhile, light the grill well. While baking the mackerel, smear it with olive oil and lemon juice.
When it is baked, add a little pepper.
Serve with potato salad.
