Heat the oil in a non-stick frying pan. Fry the courgette for approx. 10 mins., turning occasionally, then remove. Fry the gnocchi in the same pan for approx. 5 mins., add the spinach, pine nuts and courgette, cook for approx. 5 mins., then plate up. Melt the butter in the same pan until it turns frothy and tastes nutty, drizzle over the gnocchi.
