Preheat the oven to 150° C or 300° F.
Remove the kale leaves from the stems and tear the leaves into large pieces, the size of chips.
Wash and dry the leaves well
Put the kale leaves in a large bowl and massage in the oil until every part is well coated. Add the salt and spices if using and mix well
Spread the kale into a single layer on a baking sheet lined with parchment paper.
Bake for about 10 minutes, rotate the pan, and bake for another 12-15 minutes. Watch them closely as they will go from perfectly crispy to burnt in a flash.
Enjoy immediately because they’ll lose their crispiness after a while
