Putting them together:
Wash potatoes well. Preferably using a Food Processor or slicer attachment, slice potatoes very thin leaving peel on. Rinse again under cool water.
Bring to soft boil and cook for 10 minutes.
Drain vinegar. Spread potato slices on a baking sheet and drizzle with just a little bit of vegetable oil. Toss to coat. Sprinkle with salt.
Bake at 400F for about 15 minutes or until brown and crispy, tossing once with spatula!
