Make 2-3 deep cuts in the chicken thighs. Place them in a glass shallow dish. Grind the tomatoes, tomato paste, sugar, chili sauce, soy sauce, ginger, garlic and lime juice to make a smooth mixture. Pour this over the chicken pieces. Refrigerate for 3 hrs. Preheat the oven to 375°F. Arrange the marinated chicken pieces in a ovenproof roasting tray and pour the marinate over them. Cook for about 45 minutes or until the chicken is tender. Serve hot.
