Preheat the oven to 400 degrees F.
Season the chicken with ground cinnamon, star anise, salt & pepper.
In a wide, deep, oven-safe skillet, heat oil over medium high. Add each piece of seasoned chicken, skin-side down and fry for a few minutes or until golden. Flip and cook for a few more minutes. You're not cooking the chicken all the way through, just developing good color on the skin.
Add your grapes to the skillet and transfer to the oven. Bake for 10-15 minutes or until chicken is cooked through and reaches an internal temperature of 165 degrees F.
Remove from the oven and top with fresh thyme and blue cheese. Serve over arugula with lemon slices and zest, if desired.
