Tear kale leaves off of stems into bite-sized pieces.
In a large bowl, drizzle olive oil and sprinkle salt and pepper over leaves. If using, add lemon juice here as well. Massage the ingredients into the kale with your hands to ensure the leaves are coated.
Lay out on a baking sheet in a single layer (I like putting the leaves face down). Sprinkle nutritional yeast on top, if using, then bake 8-9 minutes. Your oven may vary and they burn quickly so keep an eye out starting at 8 minutes.
