Kitchen Staff Tip: If you're in a pinch for time, you may prepare this recipe in the microwave by preparing the squash as directed, placing cut-side up in a microwave- safe dish, and cooking on high for 6 or 7 minutes.
Make sure to rotate the squash halfway through cooking time. Top squash with the apple mixture, cover with vented plastic wrap, and microwave on high 4 to 5 minutes or until apples are tender.
