Peel and core the pumpkin and cut into 1 cm cubes. Finely chop the onion. Wash the zucchini and chop or grate.
Fry the pumpkin and onion in a large pan in olive oil for about 5 minutes. Deglaze with a good dash of white wine and steam in it. After 3 minutes add the zucchini and continue cooking until the white wine has boiled down. Add the cream, season with two teaspoons of vegetable stock powder, salt, pepper and a little nutmeg and simmer for another 3 - 4 minutes.
Add the finished gnocchi and cook for 2-3 minutes so that the sauce thickens. If desired, the sauce can also be made more liquid with a dash of milk.
