Heat olive oil in an oven-safe skillet. Season the chicken breasts liberally with salt & pepper on both sides, and add to skillet. Sear for 3 minutes on each side, until nicely browned. Transfer the skillet to the oven (or place chicken in a separate baking dish), and bake for 15-20 minutes until the chicken is fully cooked (165-170F in the center).
Top each chicken with 2 tablespoons Caramelized Onion Jam
