Peel onion, garlic and carrot. Wash the carrot and dice everything finely
Heat the oil in a pot. Sauté onion and garlic until transparent. Brown the carrot and soup vegetables. Sprinkle with flour and sauté. Stir in tomatoes, 1/8 l water and stock. Bring everything to the boil, cover and simmer for about 10 minutes
Season the soup to taste with salt, sugar and cayenne pepper. Put sour cream as a blob on top and sprinkle with some pepper. Add the bread rolls
Instead of the bread garnish, you can also cook 20 g of noodles or rice (makes 60 g) and add to the soup. The calories remain the same. 1 teaspoon (5 g) grated Parmesan cheese instead of sour cream gives the soup an Italian touch
