This is one of the easiest "hands-off" one-pot rice dish I have ever come across! To make a vegetarian version, just swap out the Chinese sausage and oyster sauce with vegetables/mushroom mixture/vegi-meat and vegetarian oyster sauce.
I am looking forward to making this earthy soup on cold days. This recipe is adaptable and versatile. For a 100% vegetarian version, simply use a vegetable stock or plain water in place of chicken stock. Once the basic technique is mastered, the possibilities are endless.
