Chicken Noodle Soup

I made a chicken noodle soup the other night based on this recipe. It was delicious but not devoured by the kids. The chilli could have been responsible, but also soup is a bit tricky for kids. The noodles were fun for them both though. :)
Here's my version.

~ 400g chicken breast, cooked and shredded. (I actually used chicken leftover from a stir-fry the night before and they were tenderloins, my favourite bit of the chicken)
125g rice vermicelli (Changs do a pack of 4 individual portions and I used 2)
1L chicken stock
1L water
2 carrots, diced
2 sticks celery, chopped
1 onion, chopped
2 cloves garlic, chopped
2 tsp dried rosemary
1/4 tsp dried chilli (up to 1tsp if you like it hot and don't have to worry about kids not liking it)
salt and pepper
3/4 cup fresh parsley (I didn't have any so didn't put it in, but I can imagine it would be better with it)

Heat 1 tbsp oil in large saucepan over medium heat and add onion and garlic. Stir for a couple of minutes until softened. Add carrots and celery and cook, stirring regularly until vegetables are slightly softened (6mins or so).
Add stock and water to pot and bring to boil. Season with salt, pepper, rosemary and chilli.
Add chicken and parsley. Simmer uncovered for 15-20min.
Add noodles and simmer for 5min.
Season with pepper as required and serve.
