I wouldn't stuff the chicken...you are going to need to cook it all the way through if you do and it's going to require more cooking. Some chefs actually don't recommend stuffing birds anyhow because the stuffing (be it veggies or stuffing or whatever) can get contaminated by touching the raw chicken on the inside. Then if you can't get the stuffing up to a certain temp to kill the potential nasties, it might not be safe to eat. And if you do get it up to temp on the inside, the outside of the bird is WAY over done.

If you could put something inside the chicken which would help cook it from the inside, you'd be laughing. Maybe a case for beer can chicken?
