Sorry noone has replied to this thread.
Spaghetti squash isn't exactly like spaghetti, but it does have the same look and somewhat the same texture as pasta aldente.
I find the easiest way to cook it is to slice it in half length wise, scoop out the seeds and cook open side down in the microwave in a pan of about 1/4 inch of water. Cook for about 8 minutes, or until finger print on the top leaves a little transparent circle.

When it's done, scoop out the insides with a fork and serve either plain with butter, or as you would pasta.
