This squash soup is a delicious and hearty vegan soup, with Thai-inspired flavors. It is a perfect fusion of western and Asian ingredients. The sweet butternut squash, little spice kick from Thai curry paste, with a little sour lemon juice make this soup a great cold-weather soup. This recipe is also vegan too. All breads go well with soups, but since butternut squash soup is smooth and relatively thick in texture, I suggest pairing it with crispy breads for contrast.
