Dessert Vegetable

I get an organic produce delivery every other week, and this week I have a couple of butternut squash - so I'm making this! Brown Sugar, squash and onions - how can I not want that!  When Matt was out of town a few weeks ago the neighbors fed me and the kids one night, which was such an amazing gesture I still can't figure out how to thank them.  But they made this, and it was like a dessert vegetable - and I love dessert vegetables....oh lord, love.  But, I've only got enought for me, so I'm making it at lunch so I don't have to share :).
