Combine the ingredients "for paste" in a bowl and coat the chicken well. Set aside for 30 minutes.
In a wok, heat coconut oil and add the marinated chicken into it and cook on meduim-low flame, stirring in between to ensure that the chicken does not stick to the pan.
When the chicken is half done, add in the sauces and keep cooking till done. Sprinkle water occasionally if needed, but the chicken should cook in its stock.
Finally add the onion, capsicum and green chillies and cook for a further five minutes. Switch off and serve warm.
