bake the potatoes in a 350 degree oven until just baked through. The time it takes depends on how big your potatoes are.
when the potatoes have cooled enough to handle, cut each potato in half. Then slice each half across the width in 1/4 inch slices but keep the potato in tact.
oil a baking sheet and take each sliced half potato and fan it on the oiled pan.
brush all the potatoes with oil and salt liberally.
bake in a 400 degree oven until browned underneath. (about 30 to 45 minutes)
