Heat conventional oven to 425 deg F. Spray 15 1/2 x 10 1/2" jelly roll pan with nonstick vegetable cooking spray. Set aside. Using thin slicing blade of food processor or very sharp knife, cut potato into 1/8" slices. Place slices in bowl of ice water to prevent darkening. Let stand for 15 min. Remove potato slices from water and blot dry with paper towels. Arrange slices in single layer on prepared pan. In small bowl, combine chives and garlic powder (original recipe included salt). Sprinkle evenly over potato slices. Bake for 15 - 20 min, or until crisps are brown, rearranging twice during baking and removing as they brown. Place browned crisps on cooling rack. Cool completely.
