Cook the potatoes with their skins in salted water until cooked, drain, peel and press through the potato press. Coarsely grate the zucchini, peel and finely grate the onion. Heat the oil, sauté the onion and zucchini for 3 minutes, fill up with the whipped cream, bring to the boil once. Mix the zucchini vegetables with the potatoes and parsley, season with salt, pepper and nutmeg.
Fried eggs and crispy fried bacon go well with it.
