quinoa chicken parmesan soup

I went into making this soup with high hopes but a little reservation.  Quinoa with a parmesan flare?  I wasn't sure.  I am SO glad I made this soup because it's terrific!  I will be making this one again and again.  I am excited about the leftovers because it made a huge amount. (Sorry, bad picture.  It looks delicious and smells divine in real life.)
