Step 1

In a measuring cup or small bowl, whisk together lime zest, lime juice, olive oil, salt and mint.

Step 2

Place boneless skinless chicken breasts in a heavy duty one gallon zip top bag. Pour marinade into the bag.

Step 3

Seal the bag, removing as much air as possible. Place bag on a large plate in refrigerator. Let chicken marinade for a minimum of 2 hours (or as long as overnight) flipping bag a couple times to ensure good coverage on all sides.

Step 4

Preheat grill to medium (about 325-degrees F). Place marinated chicken breasts on the grill; pour or brush on the remainder of marinade onto the chicken breasts. Cook about 7 to 10 minutes per side. Check for doneness with meat thermometer.

Step 5

Remove from grill, let rest 10 minutes before slicing.
