Bring plenty of salted water (1 litre per 100 g of pasta) to the boil. Add the noodles and cook for the time indicated for their type.
Heat the olive oil in a frying pan, briefly sauté the onion and garlic, then add the mussels (with the broth), fry briefly, deglaze with white wine. Add the strained tomatoes and simmer the sauce for 10 minutes on a lower heat.
Season the sauce with lemon juice, salt, pepper and sugar, mix in the chopped herbs.
Drain the pasta, mix with the sauce and arrange on the plates. Serve immediately.
