Wash and pierce spaghetti squash a few times with a fork or sharp knife. Microwave whole in a casserole dish for 2 - 3 minutes to soften skin.

Cut in half lengthways with a sharp, serrated knife. Remove seeds with a spoon.

Place cut side down in casserole dish; add 1/4 cup water, cover with plastic wrap or lid and microwave 8 - 10 minutes.

Pull out the strands with a fork; add salt, butter and parmesan cheese or cinnamon sugar to taste.
