This recipe came about by visitors arriving unexpectedly and therefore needing something easy in a hurry that would feed 5/6 people. Also, being older, I had to keep in mind the fact that hot curries and spices don't always agree with the ailments often suffered by an ageing population.
If you don't have any leftover veges, prepare a mix of potato, sweet potato and any other veges you like before you put recipe together. Last time I made it I only had roast pot. left so steamed some sweet pot and beans before I started putting everything else together. If in a hurry, instant rice packets can be used.
