How can I cook squash in the microwave efficiently?

To cook squash efficiently in the microwave, first wash and pierce the squash with a fork. Then, place it in a microwave-safe dish with a little water. Cover the dish with a microwave-safe lid or plastic wrap, leaving a small vent. Microwave on high for 5-10 minutes, depending on the size of the squash. Check for doneness by piercing with a fork. Let it cool before handling.
