Preheat oven to 400°.
Scrub potato with a brush. Cut potato lengthwise into very thin slices using a mandoline slicer.
Combine potato slices and oil in a large bowl. Add cheese, chives, and salt, and toss gently to coat.
Arrange potato slices in a single layer on baking sheets coated with cooking spray. Bake at 400° for 18 to 20 minutes or until golden.
Note: Chips will brown at different rates. Watch chips carefully, and quickly remove individual chips from the oven as they become golden.
