Heat oil in medium saucepan; add onion and sauté until tender. Add spinach, cover pan with lid, and cook until spinach is wilted.
Add all ingredients to WildSide or FourSide jar. Secure lid and select “Soup.”
For a raw and vegan soup, omit the oil and use water instead of vegetable broth. Use soaked beans instead of cooked beans. Do not cook the onion and spinach before adding them to the blender.
