Skillet Chicken With Tomatoes, Pancetta and Mozzarella

Ended up pretty bland, kinda just tasted like chicken. Used boneless skinless thighs so that probably hurt the flavor. Improvements for next time: add a bit of sugar to the sauce, simmer the sauce for longer and/or use diced tomatoes instead of whole, use skin-on chicken, use less chicken, add the pancetta to the sauce while it simmers, add olives or capers.
