Juicy chicken breasts seared to a golden brown, finished in a tangy-sweet balsamic sauce with blistered cherry tomatoes and gooey mozzarella, all made in one pan for easy cleanup.
Use boneless skinless chicken thighs for darker meat, or substitute bocconcini with sliced mozzarella if needed. For a sweeter glaze, stir in 1 teaspoon honey with the balsamic.
