Aunt Stacey's Sweet Potato Chips

My sister-in-law made these for us on her last visit and I'm addicted!  This serves 2 as a side dish.

2 sweet potatoes, cut into thin half moons (cut sweet potato lengthwise in half and then cut into half moons).
1 TBS olive oil
sea salt
freshly cracked black pepper

Preheat oven to 425.  Place cut sweet potatoes on cookie sheet and toss with olive oil--make sure that they're well spread out.  Season with S&P.  Bake for about 30 minutes, stirring every 10 minutes or so.  Sprinkle with more salt and pepper if desired.  Best served hot!
