3Tbspextra-virgin coconut oil / grape seeds oil or any oil of your choice
Small bunch of fresh coriander leaves
Preheat a large heavy-bottom pot with a lid with oil. Add in the onion, garlic, ginger, turmeric powder, lemongrass into the pot and saute until very fragrant, and the onion is soft, about 2 minutes
Add in the chicken pieces and cook until they start to turn color and then tip in the tomatoes and cook until the tomatoes are soft, about 5 minutes or so. There should be some juice in the pot now. Add the chicken stock, lower the heat to simmer and partly covered until the chicken is cooked through, about 10 minutes. Add in the kaffir lime leaves and cook for another 5 minutes. Season with salt and have a taste and adjust to your liking
Just before serving, ladle the soup into serving bowl and sprinkle on the coriander leaves and serve immediately
It's hard to find replacement for kaffir lime leaves. If you can't find any, you can go without them in the recipe.
