Put the spinach in a large colander set over the sink. Pour boiling water over, then leave to cool and drain. Squeeze out the excess moisture, then blitz in a food processor with the soft cheese, breadcrumbs and some seasoning. Rub some oil on your hands, then shape the mixture into 20 balls. Cook in a pan of boiling, salted water for 2 mins. Scoop out, season and drizzle over some oil and scatter over the parmesan.
