It's not quite turkey-carving time just yet, but summer's over and that means the return of autumn veggies. Chef Robert Fathman's Blue Hubbard Squash Soup is a perfect way to ring in soup season: The flavors of fall without the weightiness of winter flare.  This recipe is perfect for a crowd (or for smaller groups, halve the measurements and freeze what is left over!)   Fatham suggests garnishes like andouille sausage, bacon, croutons, sage and/or truffle oil to mix things up!
