you can add what you like! I just kept it simple for now, might add other stuff in later. It kinda comes out as a soup, its hard to describe really. also if you put more chicken in then it really doesnt come out like a soup, there will be no liquid at all, its quite mushy, doesnt look nice but it tastes good (well to me and Caleb anyway! lol) The egg goes in after the heat is turned off but very soon after, like 10 seconds
