Preheat oven to 250 degrees.
Using a mandoline, slice sweet potatoes as thinly as possible.
Pat sweet potato slices dry with paper towel, add to medium sized bowl.
Spray slices with olive oil mist (or add 1 tsp olive oil) and generously sprinkle with salt, pepper, or any other herbs you'd like to add.
Lay slices on baking sheet lined with parchment paper, do not overlap.
Bake at 250 for 1 hour, until crispy.
Turn oven up to 350 and let chips brown very slightly. Watch chips and make sure they do not burn.
If you'd like them cool, place on a cooling rack and let sit 10 minutes.
Serve and enjoy!
