Ingredients

1 medium sweet potato
1 medium russet potato
1 medium yam
1 turnip
2 tablespoons olive oil
Pinch of garlic powder
Pinch of onion powder
1 tablespoon rice vinegar
1 teaspoon soy sauce

Directions

Peel the potatoes, yam and turnip. Slice each very thin on a mandolin or slicer. The thinner the slices, the better they bake. Combine remaining ingredients in a bowl and whisk. Pour into a clean spray bottle with a pull trigger. Lay the potatoes, yam and turnips on a non-stick baking sheet. Make sure not to overlap the slices. Spray with olive-soy mixture. Bake in a 320-degree oven until golden in color. When they cool, they will become crispy.
