Pre-heat the oven to 350.
Slice the potatoes into thin rounds.
Coat a baking sheet in a thin layer of extra-virgin olive oil (about 2 tablespoons).
Place the potato rounds / slices on the baking sheet.
Turn them over and slide them around to get olive oil on both sides of the potato rounds.
Sprinkle potato rounds with sea salt or Herbamare, and other herbs or spices if desired.
Bake for about 1 hour, or until slightly browned and crispy.
You are now done. Enjoy!
