Three hours before the guests arrive,she begins to prepare the meal.Cathi begins by first cooking the rice and places it in a serving dish to cool.Next she cuts the chicken breast into strips on a cutting board,places the chicken back into the dish and then seasons it.While the oven is preheating she chops unwashed salad ingredients on the same cutting board where she cut the chicken,but she uses a clean knife.She combines the salad and places it into the serving bowl.One hour before the guests arrive,she places the chicken into the oven to bake.She stirs the rice and adds nuts and a few herbs.Just as the chicken is finished,the first guests arrive.
