Our CSA packet from last week had a butternut squash. The family (my parents are still here) agreed on a soup (with home-made pizza) for dinner. It has been a cold enough summer to warrant some soup. Especially on Monday night.
This recipe is modified from the Moosewood Recipes. That's where the idea of sage warmed with butter came from - that's not me! Here is the link to the recipe - Moosewood's Butternut Squash Soup
