When doing a dish like poached chicken with vegetables or corned beef it is a good idea to put your vegetables in a cheese cloth, tie it up and lower it into the pot. Let a piece of the string hang out of the pot but be careful with contact with any flame. This means that you can take out all the vegetables at once if the main ingredient is not quite ready. It also allows you to have vegetables free of peppercorns and other spices. When you main ingredient is ready you just put the vegetables back in , heat them up and let everything sit. This method makes a big difference and saves a lot of washing up.
