STEP
Take the nice big mussels, scrape and wash them well, open them with a small knife holding the fruit only on one side and not letting the two valves detach completely, place them on a separate tray and keep their water, when you open them, in a small cup and put it aside, it is important to filter it with a cotton gauze to eliminate any residues;
Now prepare a mixture with the bread previously soaked in water (well squeezed), the whole eggs, a clove of garlic and chopped parsley, pepper and grated cheeses. The mixture must be compact, so that it does not come out of the mussels during cooking;
Using a spoon, fill the previously opened mussels with the mixture and close them tightly;
In a large saucepan, fry the finely chopped white onion and a clove of garlic in its skin with a little olive oil, add the tomato puree and cook for about 15 minutes;
Add the mussels, the filtered mussel water and cook for another 20 minutes over medium heat (turning them gently only once halfway through cooking;
Turn off and serve hot…a truly excellent preparation, finger-licking good!!
