Love, love, love spaghetti squash!
I cut it in half. Scoop out the seeds. Place cut side down in a pan with about a half inch of water in it. Bake approx 1 hour. Scoop out and mix with cinnamon and a bit of sweetener if you have sweet tooth.
After baking if you scrape it out carefully with a fork you get the best 'spaghetti' effect. I love it anyway you would use spaghetti - with tomato sauce and parmesan; meat sauce; cream, parmesan, garlic and parsley.
Enjoy!
