Rinse the red lentils thoroughly under cold water until the water runs clear.
Peel the carrot and slice both the carrot and zucchini into small, uniform rounds to ensure they steam quickly and evenly.
Place the lentils, carrot slices, and zucchini rounds into a steamer basket over a pot of boiling water.
Cover and steam for 15 to 20 minutes, or until the lentils are completely tender and the vegetables are soft.
Transfer the steamed lentils and vegetables into a high-speed blender.
Add the silken tofu, nutritional yeast, fresh ginger, ground turmeric, sea salt, and black pepper to the blender.
Pour in the vegetable broth and blend on high speed for 60 seconds until the soup is perfectly smooth and velvety.
In a small ramekin, whisk the white miso paste with one tablespoon of warm water to dissolve it, then stir it into the blended soup.
Pour the soup into a warm bowl and serve immediately while hot for maximum digestive comfort.
