I think it is also easy to cheat by enhancing the packet stuffing if you don't have the time to do it properly. I often use a chopped onion, which I boil in a small quatity of water until softened and use the onion and water to make up the packet stuffing. We grow sage in the garden, so I get about half a dozen leaves and chop them and add it to the stuffing. I also often add the grated rind and juice of half a lemon, with a flat teaspoon of sugar, then microwave for a couple of minutes and leave to cool, before stuffing the bird.
I also often use just a five teaspoons of packet stuffing and cook it for two minutes in the microwave with some water and then use the mixure to stuff just one breast of chicken. Just cut into the underside of the breast with a sharp knife and fill it with the stuffing, before wrapping it in a rasher of bacon and high speed roasting it for 25 minutes in an oven at 210 degrees, if you want a really quick roast dinner!
