Before chopping the lemongrass, be sure to cut off the spiky green top and enough of the bottom to eliminate the woody core.

Though these breasts are great served hot off the grill, they’re also fine served cold in the coming days, either plain or sliced atop a salad. From Fine Cooking. Marinate time not included.
