Typically, I say, if you are going to cook a turkey, just go ahead and cook a whole turkey.  In this case, I needed something for the non-red meat eaters and also thought, I would have some turkey for making sandwiches.  This breast was left on the bone so it had more flavor than a breast removed from the bone.  It also enabled me to make some stock afterwards.

The weather was rainy outside, so I had to cook inside.  I roasted it the oven after making a marinade, basting mixture.
