The comforting combination of silky sweet potatoes with tangy apples ???? make this soup tasty and satisfying. I used spices such as curry powder, cinnamon, nutmeg and fresh ginger to enhance the flavour of this delicious vegan soup. This sweet potato and apple soup is packed with vitamin A, C and fiber, but the best part, the soup is low in calories only about 160 calories per cup and has virtually zero fat. I promise you, this gluten-free soup will keep your hunger at bay without the extra calories.
