Fall Flavored Tacos
After all the taco posts recently, I feel this question is topical, even as fall is (I pretend) fairly far away.
I plan to have a marriage reception in the fall, and will serve tacos, as I find these a simple to pre-prepare, yet elegant food.
Does anyone have any ideas for fall-style tacos? Salsas/vegetable slaws with more of a fall theme?
Has anyone ever tried a parsnip salsa?
Thanks for any suggestions!

I gave a bottle of the beer to some friends as a gift last year- now I lament I didn't pick up a bottle for myself at the time as well- I wasn't aware then of the beer's fame!
They reported back that their bottle was one of the recalls. But, they apparently dug the funky sour-esque off flavors of the recalled bottled.
