Heat wok and add sesame oil. Fry potatoes and carrots till it becomes a bit soft then add Chinese sausage and dried chilly. Add a bit of sugar and salt to taste. At last add sesame seed (optional). The potatoes and carrots will turn out crunchy. If you want it soft add a bit of water while cooking but I prefer it dry and crunchy.
Thanks for reading. Give it a try. It is easy and yummy too.
