Basically, any recipe for a whole chicken should work fine. You would want to cook it on the 'fast' setting so it doesn't fall apart.
If you add veggies, put them on the bottom and place the turkey on top. The turkey is done when the juices run clear when you puncture the thickest part of the meat.
With a breast, if you can figure out how to weight it down as it cools, it should 'set up' so that you can slice it for sandwiches and stuff.
I wouldn't serve this as a guest dish. It should taste good, but the color would be pallid and it would not present well for a fancy entree.
