For the healthy potato chips, first preheat the oven to 170 °C top-bottom heat.
Peel the potatoes and cut them into very thin slices with a sharp knife.
Place the chips on a baking tray lined with baking paper and drizzle with olive oil.
Bake in the oven for about 15-20 minutes (depending on the desired crispiness).
Finally, season with sea salt, cumin, etc. to taste.
