I tried it both roasted and in the soup.
We both really liked it roasted, so I ended buying some more

I tried the soup a couple of days ago and thought it was kind of bland, so maybe adding some other spice might perk it up...I am not sure what yet, but I will experiment.
I really want to tryi it roasted with something sweet like cinnamon as midwife suggested, so that will be the next batch.
Did anyone else have any luck finding the squash at their local Costco?
