3. In a small bowl, mix together the diced pear, goat cheese, thyme leaves, salt, and pepper.
4. Stuff the pear and goat cheese mixture into the pocket of the chicken breast.
5. Season the outside of the chicken breast with salt and pepper.
6. Place the stuffed chicken breast on a baking sheet and bake for 25-30 minutes, or until the chicken is cooked through and the cheese is melted and bubbly.
7. Let the chicken rest for a few minutes before slicing and serving.
