Preheat oven to 325 degrees.
Ripe off kale from stalk into 1-2″ pieces.
Place kale in a single layer on parchment-covered baking sheet.
LIGHTLY spray or drizzle with oil.
Add about a teaspoon of topping choice. If you use vinegar, coat leaves and let dry, then sprinkle with a teaspoon of sea salt.
Bake for 15 minutes; watch closely the last 5 minutes. They will crisp up more after taken out of the oven. Do not let them burn… and enjoy!
