I made some sweet potato chips/crisps this week on the fly.
No idea what the usual method is as I haven't bothered looking, but fried them in garlic infused olive oil both sides lightly, placed on a kitchen towel to take off most of the oil, lightly salted and then put them in the oven with other stuff I was cooking to crisp off. Turned out really good, will have to look up proper recipe to see if I can improve.
Feeding 50 starving marines hardly proves you're a great chef, it just means you can cook.
