When done remove from oven and allow to cool.While butternut squash is baking, soak sundried tomatoes in some warm water to soften them a bit. Wash and chop all veggies and herbs for filling.
Cook shallots in a pan over medium heat with sage, rosemary and garlic until soft. Add mushrooms and cook until most of the released liquid evaporates, then mix in spinach.

You do not want this silky smooth. Once done, add to veggie mixture and mix until combined. Set aside.
Once butternut squash is cooled, add it to a food processor, blender or high speed blender along with the cashews, walnuts and water. Blend until you achieve a silky smooth consistency. This will take longer in a standard blender or food processor. Add salt and pepper to taste.
