In a medium bowl, stir together the cream cheese, ½ cup buffalo sauce, ¼ cup Creamy Ranch Dressing, cheddar, and chives. Stir until smooth. Set aside.
Season both sides of each chicken breast with salt and pepper
Use a sharp knife to carefully cut a pocket lengthwise in each chicken breast.
Stuff each chicken breast with the filling. You may want to secure with toothpicks depending on how much filling you use.
Place a large skillet over medium/high heat. Add the olive oil and allow to heat until glistening.
Add the chicken breasts to the skillet. Brush the tops of each breast with ½ of the remaining buffalo sauce. Cook for 4-5 minutes.
Flip the chicken breasts and brush with the remaining buffalo sauce. Cook for an additional 4-5 minutes.
Flip once more, basting in the sauce if desired. Cook until the chicken reaches an internal temperature of 165F (1-2 minutes more).
Remove from the heat and drizzle with the remaining ¼ cup Creamy Ranch Dressing. Sprinkle with crumbled blue cheese.
Enjoy!
