If you want to grill it ............ this is what I do.

-Remove the breast then cut it into 1" thick slices (whatever length you like, I usually cut full length).
-Season with a little seasoning salt or rub
-place some BBQ sauce into the bottom of a container, then the slices then cover with more BBQ sauce
-leave it for about 1 hour (give or take, 30 minutes min.)
-place on a heated grill, turn after about 2-3 minutes and finished in about 6 minutes

It will not take too long to cook them this way on the grill and you will not be disappointed.

Good luck
