You only need:
about 400 g tomato juice
1 small onion
1 clove of garlic
salt / pepper
1 chopped carrot
pinch of sugar
if necessary: semolina
In a saucepan put the tomatoes, onion, and chopped carrots. Let it cook, when the soup thickens, add a little water. If it gets too thin - add a teaspoon of semolina. Towards the end remove vegetables, add salt/pepper/basil, sugar and dumplings.
To make dumplings in a little water add flour and form small beads with a spoon .
Boiled seasoned with sour cream.
I didn't have fresh basil, because my little veggie is still growin' :)
