This is a vitamin rich, naturally low calorie, high fiber, creamy indulgent bisque, that is guaranteed to warm you on these cold lingering days of Winter and Spring and just anytime you need some good comfort food. This recipe is easy to make, because you don't have to peel and dice the squash and sweet potatoes before roasting. You simply scrape the tender meat out of the skins. Panera Breads is where I had my first Butternut Squash Soup and I fell in love. I believe they use pumpkin in their recipe. I saw a recipe on the internet using sweet potatoes and I tweaked it to come up with this recipe.
