Serves 4
For preparation:
For the rice:
Clean and thoroughly scrape shells of the mussels, removing their beards. Peel and finely slice the onion.
Place mussels in a wide saucepan with the onion, the peppercorns and 300 ml water. Cover and cook on high heat for a few minutes, shaking the pan occasionally, until mussels begin to open. Strain the cooking liquid through a fine sieve. Discard any mussels that have remained closed, save some whole with their shells. Remove and save the meat of the others.
To prepare rice:
Peel and finely chop the onion, tomatoes and garlic.
In a large pan fry the onion and garlic until nearly transparent.
Add the mussels and briefly sauté them in the oil. Add the tomatoes, bay leaves and oregano. Continue cooking for a further 3-4 minutes until thick.
Heat the mussels cooking liquid in a saucepan. When boiling add the rice, stir briefly, cover and cook for 15-18 minutes until liquid is absorbed.
Transfer rice to the pan with the mussels and the other ingredients. Add half of the parsley, a little salt and pepper and the saved mussels and shells.
Leave on low heat a few more minutes until rice is ready. Sprinkle with the rest of the parsley and serve.
