Preheat oven to 375 degrees F.
Place the kale pieces on a large baking sheet in a single layer.
Drizzle on olive oil and toss until the kale pieces are coated.
Evenly sprinkle on nutritional yeast, onion powder and salt, and toss until kale pieces are well coated in seasonings.
Bake for around 8-12 minutes, or until kale is crispy, tossing halfway through, or every couple minutes at the end.
Check the kale frequently as it can burn easily.
