How to make
Clean the mackerel, rub them with salt and pour on the juice squeezed from the lemons. Leave them to sit for 30 minutes in a cool area. Heat a little oil in a pan and sauté the chopped leeks and garlic until slightly soft. Season to taste with some salt and black pepper.
Mix with the chopped roasted peppers and lovage. Arrange tomato slices in a greased oven dish, spread the fish on top and cover them with the stewed mixture.
Sprinkle it with a little fresh parsley. Arrange lemon slices, pour in a little oil, cover it with foil and put it to bake in a preheated 360°F (180 °C) oven for 40 minutes.
Remove the foil and bake for another 5-10 minutes.
