This miso soup is the vegan version of chicken soup.  It is healing, full of probiotics and tasty to boot.  If you reheat it and it tastes too salty just add more water! 
Don't heat it too high after adding the miso paste or you will kill the good probiotics.  Which are found in the paste.
If you don't want to chop all of the vegetables you can use a food processor with the slicing blade or a mandolin.
