Preheat oven to 325°F. Line a 13”x18” baking sheet with parchment paper.
Rinse kale, remove leaves from stems and tear into large pieces, spin the pieces until dry.
Place pieces of kale into a large bowl, drizzle with oil, then use (gloved) hands to turn and distribute the oil evenly.
Spread pieces in a single layer on the baking pan. Sprinkle with Greek Seasoning and Nutritional Yeast (optional).
Roast at 325°F for 12 minutes. Rotate the pan (back of the oven is often hotter) and return to the oven for an additional 12 minutes.
Allow to cool on the baking sheet for a few minutes. Kale chips loose their crispiness the longer they are out of the oven, so enjoy them right away.
