Preheat the oven to 375 degrees.
Prep the kale by rinsing it under cold water, and then laying the leaves out on a kitchen towel. Use another towel to pat the leaves until they are dry, this helps to get them crispy.
Remove the leaves from the stems, and then tear the leaves into bite size pieces. Place the kale in a large mixing bowl, and drizzle the olive oil over it. Then season with salt, pepper, red pepper, and nutritional yeast. Use your hands to massage the seasoning into the kale until it is completely coated.
Divide the kale leaves between two large baking sheets, and spread them out into an even layer on each baking sheet. You don't want them to be overlapping too much.
Bake for 10-12 minutes, until the leaves are crispy and just starting to turn brown.
Transfer to a serving bowl and enjoy! Store leftovers in an airtight container in the fridge for up to one week.
