Add the oil to a large pan and heat and then add the chicken and cook until done, about 5-7 minutes. Remove from the pan and set aside.
1 tablespoon olive oil, 250 g chicken breast
Put the same pan back on the heat and add the stock, garlic, ginger, cloves, star anise, lime juice, fish sauce, coriander (cilantro), basil and chilli and turn the heat to a simmer and cook for 5 minutes to form the broth. Remove the cloves and star anise - (these can sometimes be a bit tricky to find).
