I posted one, but it used spiralized acorn squash. I'll see if I can find it, if it's what you were looking for, great, if not, no problem.

Here's mine:

This may be a stupid question, but how do you "spiral" the squash? Is there a special tool for that?

yeah, you need a spirooli. you could just use a vegetable peeler though to make long strands.
