Ideas for a portable side dish that is sweetish, but not cloying/dessert-like - use of seasonal veggies a plus.
Another option is spiced apples: http://www.seriouslygood.kdweeks.com/2008/11/spiced-apples.html
If you're worried about sweetness, add a tablespoon or two of lime juice at the end, after tasting it. The parsnips add a fun, spicy touch to the squash. It's one of those dishes about which people will ask, "What's in this, anyway? What am I tasting?" Have fun!! ;o)
