Place the rice in a sieve and rinse thoroughly under cold water, until the water runs clear.
Spray a saucepan with low calorie cooking spray and set on medium heat. Sauté the onion, garlic and carrot for 3-5 minutes until soft.
Add the chicken stock, bay leaves and rice to the saucepan and bring to a boil. Reduce the heat and simmer for 20 minutes.
Add the cooked chicken to the saucepan.
In a mixing bowl add the egg and lemon and whisk together with a fork. While whisking add 2 ladles of the chicken stock from the pan to the bowl, this will help to stop the eggs splitting.
Once combined add this mixture back to the saucepan and stir.
Remove from the heat and season to taste, with salt and pepper.
Serve, sprinkled with some chopped parsley.
