To easily peel and cube acorn squash, first pierce the shell of the squash in several places with a fork, and microwave at HIGH 2 minutes. Let the squash cool slightly before peeling it, and then use a vegetable peeler to remove the skin. Once you've peeled it, cut the squash in half, scoop out the seeds using a spoon or your fingers, and cube it.
