Heat oven to 425°F. Wash squash; pierce several times with fork. Place squash on microwavable paper towel in microwave oven. Microwave on High 3 minutes. Let stand in microwave oven about 5 minutes.
Meanwhile, cut four 18x18-inch sheets of heavy-duty foil.
Remove squash from microwave. Cut in half; scoop out and discard seeds. Cut each half into 2 wedges. Place 1 squash wedge in center of each sheet of foil. Top each with 1 apple wedge and about 3 pork sausage links.
Bring up foil around squash wedges, forming bowl shape. Pour 1 tablespoon water around each squash; pour 2 tablespoons syrup over each sausage-apple-squash combination. Sprinkle 1/8 teaspoon cinnamon over each. Bring corners and sides of foil together; press tightly above sausage to seal.
Place foil packets, seam side up, in oven; bake 35 to 40 minutes or until squash and apple are tender. Open packets carefully to allow steam to escape. Spoon hot syrup in packets over sausage, apple and squash.
