In a prepared meat or vegetable broth (made with carrots, parsley, celery root, and onion), add finely chopped potatoes and zucchini cut into thin strips.
Cook until the potatoes are partially tender, then stir in grated tomatoes or tomato sauce to taste (the soup should have a slightly tangy flavor) and season with salt.
At the end, add spices and fresh herbs.
Serve hot, garnished with sour cream.
You will need one small zucchini, 6-8 potatoes, 2 tomatoes (or a tablespoon of tomato sauce), a carrot, an onion, a parsley root, spices, and fresh herbs like parsley, dill, and celery, along with salt.
