In a small bowl, combine soy sauce, honey, oil, lime juice, garlic, Siracha, and cilantro.
In an airtight container, pour over chicken breasts and let marinate for at least one hour, up to three hours.
Put chicken onto metal skewers or wood skewers that have been soaked.
Grill over medium-high heat, about 5 minutes on each side, until cooked through.
Enjoy!
