In a large pot, add the water and allow to boil.Once water is boiling, add in the vegetable broth cubes.Once dissolved, add in the butternut squash. Put on the lid and allow to cook until the squash is soft and cooked (about 10 minutes).Blend the soup in a blender or I used a hand blender as its much faster and no transferring of soup required.Once blended, return soup to pot if needed, add chickpeas and spinach and simmer for 10 more minutes until spinach is wilted.Serve.
