Step 1

Preheat a large, non-stick pot. Add the onions, carrots, and celery and cook until onions soften. Add the water and all remaining ingredients except nutritional yeast, parsley, and miso. Reduce heat to medium-low, cover, and cook until vegetables are tender and broth is flavorful (at least 30 minutes).

Step 2

Stir in the nutritional yeast and parsley. Place the miso in a small bowl and add some of the hot broth a little at a time, stirring, until the miso is dissolved in the broth. Add the miso broth back to the pot. Add salt to taste and serve.
