Sweet potato chips

Ingredients:
700 gms sweet potatoes
1/3 cup olive oil or coconut oil
sea salt
Directions:
Preheat the oven to 180 degrees. Line baking tray with baking paper. Use a mandolin slicer to cut the sweet potatoes into paper-thin rounds. (I set mine to the thinnest setting.) You can use a knife to do this, but it takes much longer.
Pile all the sweet potato rounds into a large bowl and pour the olive oil over the top.
Gently toss to coat every piece with oil. Then lay the sweet potato rounds out on the baking sheets in a single layer.
Sprinkle the chips lightly with sea salt. Bake for 20-25 minutes until crisp and golden around the edges. Remove from the oven and cool for 5 minutes. Then move the chips to a bowl, or plastic bag to store.
If you happen to find a few chips with soft centers, pop them back in the oven for about 5 minutes.
