Tunisian Chicken Skewers

In a large nonstick skillet, heat the olive oil. Add the onion and cook over moderately low heat, stirring occasionally, until lightly caramelized, about 10 minutes. Transfer the onion to a blender. Add the bell pepper, Peppadews and brine, raisins, pomegranate molasses, peanuts and cayenne to the blender and puree until smooth. Season the marinade with salt and pepper.

In a medium bowl, rub the marinade into the chicken. Cover and refrigerate for at least 3 hours or overnight.

Light a grill. Thread the chicken onto the skewers and season with salt and pepper. Grill over moderately high heat, turning, until lightly charred and cooked through, 10 to 12 minutes. Serve hot.
