Otherwise known as "I really need to go to the grocery store plant-based vegetable soup" made from ingredients you have on hand in your freezer and cupboard.
Combine all ingredients (except the grains) in a large soup pot.
Bring to a boil and then simmer for at least one hour. Stir occasionally.
Add 1 cup of grains and simmer 10 more minutes (or more) until grains are cooked. If the soup is too thick at this point, you can add more broth.
I love to make a big pot of soup and then eat on it for several days by adding more broth, veggies, beans or whatever I find in my "Old Mother Hubbard" cupboards. 😉
