Spray a nonstick frying pan with oil and heat. Cook the chicken for 5 minutes, turning occasionally, or until lightly browned and cooked through. Cool, cut into fine slices and set aside. Heat another spray of oil in a large saucepan. Add the spring onions and cook over medium heat for 2 minutes or until soft. Add the ginger and cayenne pepper and cook, stirring for another 1 minute. Add the stock, corn and cooked chicken to the pan. Bring to the boil, reduce the heat and simmer for 5 minutes. Stir in the parsley just before serving
