Preheat the oven to 200C/fan 180C/gas 6. Line a baking tray with a lightly oiled sheet of baking paper. To make the salsa, put the parsley + the juice and zest of the 1 lemon in a food processor and pulse until roughly chopped. Put the salmon fillets on the baking sheet. Season with freshly ground black pepper. Cook in the oven for 10 – 12 minutes or until cooked through. Serve with the salsa.
