Drizzle oil in a large skillet or cast-iron pan over high heat. Season chicken liberally with salt and pepper and place skin-side down in the pan. Sear for 4-5 minutes, flip the chicken and add the grapes.
In a medium-size Dutch oven, drizzle some oil. Once hot, add kale and onion, and sauté. Lower heat and add chickpeas, capers and a splash of chicken stock. Season with salt and pepper and cover. Let sit over low heat for 10-12 minutes or until kale becomes tender. Add the lemon juice, butter, a handful of cilantro and peppadews, and stir to incorporate. Add the cooked chicken and grapes to the pot.
