Not sure if any of your have tried Acorn Squash; I just discovered it. Only one word can describe it: Wow!!!
For myself to consider something good it needs to meet two criteria: Healthy (read: low caloric density) and easy to prepare - this bad boy covers both.
I just cut it in half, scoop the seeds of of the middle and throw it in the microwave, cut side down on a plate for about 4 - 5 minutes on high. Let it cool a little, dig out all of the goodness and mix with a little butter and salt and viola! Very tasty, very filling.
Give it a try!
