Chop carrots and onions. Saute in a large pot over medium heat until they begin to soften.
Chop zucchini and mushrooms and add to pot. Add in all remaining soup ingredients and cook over medium heat for 5-10 minutes, stirring occasionally.
Cover pot and turn heat down to medium low. Let soup simmer for another 5-10 minutes. At the point where all the vegetables are soft, the soup is done.
Top with additional spices and seasoning, if desired.
