cooking oil - enough to cover the bottom of the pot
Instructions
Peel and cut celeriac, carrot, and parsley root into small cubes.
Add the oil to a pot and heat over medium heat. When the oil gets hot, add small amounts of carrot, parsley root, and celeriac (like a few pieces of each - just to cover the bottom of the pot). Saute it for a few minutes with constant stirring.
Add the remaining carrot, parsley root, and celeriac to the pot. Add peas, cauliflower florets, Brussels sprouts, and add water. Season the soup with salt. Bring it to a boil, and then lower the heat to the lowest.
Simmer the soup for about 45 minutes or until vegetables are tender. When the soup is done, taste the soup and add more salt if necessary.
Serve the soup with soup with pieces of vegetables or with noodles.
