Heat a thick bottomed pan. Add 2 tbsp olive oil to the pan. When the oil turns hot, add the chopped onion and fry for a minute, followed by the chopped peppers. Fry for another 2 minutes. Add the diced chicken and cook until they turn white. Add the spice powders, salt and sugar and mix well. Cook for another 3-4 minutes or until the chicken is cooked through and the flavours have melded. Switch off and allow to cool slightly.
