If it's getting colder...

...try a hearty soup for lunch. How about some lentil soup with frankfurters, carrots and potatoes? Served in many corner diners or "Imbisse", this soup is an old standby. Make sure you add a spoonful of vinegar or lemon juice just before you eat it and have a Fladenbrot, Bauernbrot or rolls for dipping.
