Remove all the leaves from the stems and place them in a colander.

Rinse the kale thoroughly to remove any dirt or bugs.  Then, it's time to toss it in the bacon grease!  Warm it gently if it's solidified; it needs to be liquid for this.

Toss until lightly coated, then transfer to a baking sheet.

Spread it out so it's a single layer as much as possible.  Bake at 350ºF for 10 - 15 minutes, checking often in the last few minutes so it doesn't burn.  Remove from the oven when it's slightly crispy.  Transfer it to a plate to cool, and salt liberally.
