In a large bowl combine all of the ingredients except mint and parsley. In batches if necessary, ladle about 1/3 of the soup into a food processor and pulse, leaving mixture somewhat lumpy. Add back to the unpureed soup and continue until desired consistency is achieved. Reseason if necessary. Add herbs and stir. Ladle into chilled soup bowls and garnish with dollop of creme fraiche and additional herbs.
