1. Heat the oil in a large pan over medium heat. Add the onion, garlic and chilli flakes, and cook until softened, about 3 minutes. Add the wine and simmer until liquid is reduced by one-quarter, about 5 minutes.
2. Add the mussels and tomatoes, and bring to a boil. Simmer, covered, stirring occasionally, until the mussels open, about 5 minutes. Discard any unopened mussels.
3. Transfer to a serving bowl and stir in the basil. Season with salt and pepper, to taste.
