1. Add the poached chicken ingredients to a medium-sized saucepan and place over low heat,so that it is just below simmering. Cook for about 1 hour or until the chicken is cooked through and just firm to the touch.
2. Gently remove the chicken,place into a bowl and shred the meat using two forks. Reserve the poaching liquid and add a tablespoon or so to the shredded meat.
3. To make the nuoc cham dressing,place the fish sauce,vinegar,sugar and 100ml water in a pan over medium heat and stir to combine. Bring the mixture to just below boiling point,then set aside. Once cool,add garlic,chilli and lime juice and stir to combine.
4. Bring the reserved poaching liquid to a rolling boil. Add the noodles to the pot (if the noodles aren't generously covered,top up with a little chicken stock) and cook for 3 minutes (or for length of time suggested on packet instructions).
5. While the noodles are boiling,add all the salad ingredients to a large serving platter or bowl. Strain the noodles and add to the serving bowl. Top with shredded chicken and garnish with fried shallots,peanuts and extra Thai basil. Drizzle with nuoc cham dressing to taste,then serve.
