Remove the stems of the kale leaves. Rinse under running water and dry thoroughly. You can use a salad spinner.
Brush oil on the leaves. Set aside.
Line a baking tray and place the kale leaves on it. Tear the leaves into bite sized pieces and arrange in a single layer. Transfer to the oven and bake for 10-15 mins or until crisp.
Meanwhile, to make the dressing, combine together yogurt, garlic, lemon juice and salt in a small bowl.
When kale is ready, transfer to a serving bowl. Scatter over peanuts. Drizzle with yogurt dressing.
