Preheat oven to 175°/350° c/f
Wash the kale, de-stem, and tear into chip size peaces.
Place in a large bowl, drizzle in the oil and massage into kale leaves.
Place kale on baking sheet lined with parchment paper. Careful not to overlap the leaves too much.
Bake in the oven for 10-20 minutes, keeping a careful eye on the kale. It should brown and crisp up but not burn.
Sprinkle with sea salt and nutritional yeast, and place on a dish, once cooled.
