-2 white sweet potatoes, long skinny shape if possible
-olive oil spray
-salt to taste
Preheat oven to 400 F. Peel sweet potatoes and slice into rounds, making the rounds as thin as possible (slice with a mandolin if you have one!) Line a baking sheet with parchment paper and spray with olive oil spray. Place rounds on parchment and spray tops of potatoes with olive oil spray. Lightly salt and put in the oven.
Cook for 12-15 minutes, flip rounds when the underside is lightly browned and cook for an additional 10-15 minutes. Baking times will vary depending on how thin your rounds are cut. They are finished when both sides are golden brown.
