Mix together the flour and paprika
and gradually stir in a little of the stock to make a smooth paste.
Bring the remaining stock to the
boil.
Stir a little into the paste,
return to the pan and bring back to the boil, stirring.
Add the leeks, carrots, cabbage and
tomatoes, and season with salt and pepper.
Cover and simmer for about 40
minutes, or until the vegetables are tender.
Adjust the seasoning if necessary.
Serve with cheese toasts.
Alternative Suggestion :
Particularly if using brown stock
as the base, you might like to make the soup even more substantial
by serving tiny dumplings instead of cheese toasts.
Add to the soup 10 minutes before the
end of cooking time.
