Roasted sweet potato chips 烤甜薯片

Adapted from Joy of Cooking. I used the Japanese sweet potatoes in this picture. Any types of sweet potatoes will do.

Directions: Cut sweet potatoes into slices about ¼ inch thick. Spray olive oil all over the slices. Roast at 450 degree for 10 minutes. Then turn over and roast for another 10 minutes or until golden brown.
