Are you familiar with this vegetable? I wan't until last year, now I really enjoy it. It's very easy to cook and is very versatile. To cook it I just slice it in half long way, turn cut side down on a pan and bake at 350 degrees for about an hour. It's done when you can easily pierce the skin with a fork. Then I scoop out the seeds and discard. Next I use a fork to dig out the insides and that's all there is to it.
I'll be planting some spaghetti squash in my garden this year! Also, you can cook and then freeze it for later use as well!
