Turn off heat, put the lid on and let infuse for 20-30 minutes before serving.
You can make diet soup, in which case you won't fry the vegetables - it will still be good, but maybe not as colorful. To do this, just boil everything together: the roots, the meat, the diced tomatoes and the oil. They will all cook at the same time and the taste will be just as good.
Enjoy!
