Heat cooking oil in a pot and fry the onion until soft.
Add the Rajah Medium Curry Powder and Robertsons Barbeque Spice and allow to fry for one minute to release the flavour and aroma.
Add the chicken pieces and fry until well browned on all sides.
Add the sweet potatoes, water and Knorrox Chicken Stock Cube.
Bring to the boil and allow to simmer partially covered for 20 minutes or until the vegetables are tender.
Just before serving mix the Knorr Brown Onion Soup with four tablespoons of water to form a smooth paste, add it to the pot together with the frozen corn and allow to simmer for ten minutes until thick.
