Sweet Potato Vichyssoise by My New Roots. I love Vichyssoise (that is the very fancy name for the rather humble potato-leek soup), but I wanted to make a really healthy version, without potatoes and all the dairy.
Sweet Potato & Red Lentil Soup with Aubergine & Kale Topping. Made this soup with a few substitutions: chicken stock instead of water, and 3 sweet potatoes + 2 carrots. Used potato masher instead of immersion blender for a chunkier soup.
