Garlic and Vinegar Kale Chips (Sept 2013 – Yum!) Preheat oven to 200 degrees. Toss the kale with 1 tablespoon of olive oil and 1 tablespoon of vinegar. Sprinkle 1 tablespoon of garlic and parsley seasoning, or your choice of seasoning on top. Give the kale another toss to coat the kale in seasoning. Spread the kale evenly across a baking sheet. Sprinkle extra seasoning on top. Note: Another recipe says you can bake for 15 to 20 minutes at 300 degrees – could try that too.
