Cover both sides of the chicken with the salt and pepper and set aside.
In a sauté pan on medium high heat, heat the olive oil. Add the chicken into the pan and cook each side, about 7-9 minutes per side, until the chicken reaches an internal temp of 165F or 74C. Remove from the pan and place on a plate.
Do not clean the pan and reduce the heat to medium. Then add the sage, shallots, brown sugar, maple syrup, mustard, bourbon, and peaches to the pan. Cook for 7-10 minutes until the peaches are soft and the sauce thickens.
Return the chicken to the skillet; heat just until warm, spooning the sauce over the meat.
