"Salsa verde just means 'green sauce'. In Italy, salsa verde is traditionally made with parsley, all kinds of different herbs, lemon, olive oil and capers. In this version, I've used rocket, which gives the sauce a peppery, nutty quality. This sauce is so good it can be used on anything from chicken and fish to veal or even pork chops. The scallops can be replaced with any other shellfish - prawns, clams or mussels" - Joanne Weir.
