Well, I never just used the breast, I keep the whole bird together like a chicken.
I do Like JM, roast the bird with bacon covering the breast. I also add sage over the entire surface, and stuff the inside with apple and orange slices. Helps keep it moist and adds a little flavor. Probably any fruit would do.
If just a breast, I would roast it in a baking pan, covered in bacon and your favorite poultry seasoning. Then use the drippings to make gravy. Bill
