|  2. Heat butter in large heavy-based 
                      pan. Add onion, cook over medium heat until soft. Add 
                      flour, stir over heat 1 minute or until lightly golden and 
                      bubbling. Add milk gradually to pan, stirring constantly 
                      over heat until sauce boils and thickens. Remove from 
                      heat. Stir in cheese, mustard, chicken and vegetables. 
                      Spoon mixture evenly into prepared dishes. | 
                       4. Using floured hands, knead until just 
                      smooth. Pat with hand to 13inch/25cm thickness. Cut rounds from 
                      pastry with 1⅔inch/4.5cm cutter. Re-roll pastry cuttings to cut 
                      more rounds. Place three rounds on top of each chicken 
                      pot. Brush top with extra milk. Bake for 25 minutes or 
                      until scones are browned and cooked and the chicken 
                      mixture heated through. |

                      Place flour in medium bowl. Using fingertips, rub 
                      butter into flour for 2 minutes, until mixture is fine and 
                      crumbly. Make a well in centre. Stir in milk and parsley 
                      with a flat-bladed knife. Using a cutting action, stir 
                      until mixture is soft and sticky. Turn onto floured 
                      surface. |
