Preheat oven to 350 degrees. Place chicken breast halves between two sheets of wax or parchment paper; pound with a meat mallet or rolling pin to a quarter inch of thickness.

Place 1 ounce of cheese, 2 T diced tomatoes, and about 1 1/2 T tapenade on each piece of chicken. Roll up like a jelly roll.

Heat the oil over medium-high in a large oven-safe saute pan; once hot, add the meat to sear on all sides. Once the meat is browned on all sides, transfer the entire pan to the preheated oven.

Roast for 15 minutes, until meat is cooked and no longer pink inside.

Allow meat to rest 3-4 minutes before cutting.
