Vegan Cauliflower Apple Walnut Soup with Turmeric

Heat oil in a large soup pot over medium heat. Add chopped cauliflower and carrots. Cook until soft, stirring frequently, for about 4 minutes.

Add chopped celery, apples and turmeric and stir to combine and coat all vegetables evenly. Saute vegetables and cook an additional 5 minutes.

Add toasted walnuts and stir to combine. Season with thyme if desired and salt and pepper to taste.
Add vegetable stock (adjust amount to desired thickness) and stir to combine. Bring to a boil and simmer until everything is very soft, about 10–15 minutes.

Remove from heat and carefully blend with an immersion blender or in batches in a high-speed blender until very smooth. Adjust seasonings as needed to taste.

Bring pureed soup to a boil and serve warm.
