I NEED to share this tip.  it's the best ever if you eat squash, and like it in other things than just roasted .: needing to be peeled.  Rather than struggling with those awkward curves using a knife,

use a vegetable peeler. 

one of the ones with the peeler horizontal to the handle might work better than one paralel to the handle, but either work.  I've tried it by leaving the squash whole, and chopping it up first, I still don't know what I like better.  But I do know, I like the peeler!

happy squashing.
