Here’s how you do it

1. Preheat the oven to 200℃.
2. Bring a large pan of salted water to boil. Turn off the heat once the water is boiling, add the gnocchi and leave it to stand for 2 minutes before draining.
3. Put the drained gnocchi into a roasting tin, stir in the olive oil and season with salt and pepper. Add the tomatoes, spinach, ricotta and lemon zest. Give it a good stir then put in the oven for 30 minutes.
4. Five minutes before the gnocchi is ready, sprinkle over the parmesan and return the tin to the oven. Serve with a green salad on the side.
