Key West Grilled Chicken

After following a post on pinterest, it led me to Key West Grilled Chicken http://www.grocerybudget101.com/content.php/322-Key-West-Grilled-Chicken .   I very rarely marinate my chicken (crazy, I know), but have been wanting to mix it up a bit with the chicken breasts.  This one was good. Next time, I'd add a little something (maybe a chopped up grilled jalapeno) to the marinade, but this definately whet my appetite for trying some new marinades, so tell me...what are some of your favorites?
