Wash and dry squash well.
Pierce squash several times with a fork.
Place squash on two layers of paper towels. Microwave, uncovered, on high 5 to 6 minutes or until slightly tender. Cut ends off squash and discard seeds. Slice into 1-inch thick slices. Arrange squash slices in a lightly greased 13 x 9 x 2-inch baking dish.
