1. Prepare the Chicken: Pat the chicken cubes dry with paper towels. Season the chicken evenly with salt and pepper.

2. Heat the Skillet: Place a large, oven-safe skillet over medium-high heat. Add the olive oil and let it shimmer.

3. Sear the Chicken: Add the seasoned chicken cubes to the hot skillet in a single layer. Sear for 3-4 minutes per side until golden brown. Cook in batches if necessary.

4. Create the Glaze: While the chicken is searing, whisk together the cranberry sauce, BBQ sauce, orange juice, orange zest, and apple cider vinegar in a medium bowl until well combined.

5. Combine and Simmer: Once all the chicken is seared, return it all to the skillet. Pour the cranberry orange glaze over the chicken, making sure each piece is coated. Bring the mixture to a gentle simmer, then reduce the heat to medium-low.

6. Cook Until Done: Cover the skillet and let it simmer for 10-15 minutes, stirring occasionally, until the chicken is cooked through and the sauce has thickened slightly. The internal temperature of the chicken should reach 165 F (74 C).

7. Serve with Garnish: Remove the skillet from the heat. If desired, sprinkle with fresh chopped parsley or chives before serving.
