I actually made this a little while ago and just never got around to posting it, so it could be a little late in the season for winter squash. You could probably find some, but if not then you'll have a tasty meal planned out and ready for the fall.
I went a little crazy with my spices (see below). I LOVE cinnamon so I put a ton on top and then mixed it all inside with the squash "meat". If you have a really fresh squash the flavor will be so delicious you really won't need much in the way of seasoning.
Enough talking, enjoy!
