• Peel and chop the onion and toss in the oil.
• Second, there are the carrot pomace - I got this fresh from making a carrot juice (see picture with the juicer) and then briefly swirled it in with the tomato juice and brought it to a simmer. Season the whole thing with a little vegetable salt and simmer gently for about 10 minutes.

To the side dish

• Boil the penne in water and then drain it in a colander.
• Put the penne in a bowl, season with vegetable salt (I don't season the cooking water because I want to use as little normal salt as possible), add the chopped parsley and the oil, mix everything well and add a layer of bread.
