Preheat oven to 150 degrees C

Make sure the kale leaves are completely dry and rub the leaves well with some olive oil

Place on a baking sheet making sure the leaves do not overlap

Sprinkle with some coarse salt and bake for 5 minutes

Rotate the tray and bake for another 3 - 5 until crispy but not burnt (the leaves should start to sizzle from the oil)

Remove from the oven and place on a cooling rack for a few minutes

Kale chips are best eaten within an hour or so
