Preheat a grill or grill pan over high heat.
Lightly coat chicken with oil and sprinkle each evenly on both sides with the salt and pepper. Grill chicken breasts for about 4 to 5 minutes on each side, or until thoroughly cooked; the meat should be solid white throughout and the internal temperature will read 165 degrees F. Remove from grill and immediately top with Cilantro Herb Butter. Garnish with parsley, if desired. Serve as butter is melting.
Follow the Scampi Butter recipe, but use only half of the garlic, and replace the parsley with 2 tablespoons minced fresh cilantro.
In a bowl, whisk all ingredients until thoroughly combined. Refrigerate until ready to use. Use the Scampi "base" to make different flavored butters.
