• Mix tomato, vinegar and sugar in a bowl.
• Spoon the tomato mixture into the pockets and add the spinach and cheese.
• Keep the filling in place by tying the breast pockets with kitchen string or using toothpicks.
• Heat the remaining oil.
• Brown the chicken in the pan, place on a baking tray and cook for 10 minutes.
• Remove the string/toothpicks and serve.
