Spaghetti squash is such a nutritious and low calorie substitute for pasta. Many recipes call for baking. I have found that after cutting the squash lengthwise, scooping out the seeds, and microwaving cut side down for about 10 minutes (depending on the size), it is perfectly done. The added bonus is that the seeds can be saved for planting. I simply wash the seeds and leave them out for a few days to dry, then store in a paper envelope.
