Combine lime juice, honey, jalapeno peppers, cilantro, salt, pepper, and garlic powder in a food processor and blend until smooth. Pour mixture into a large resealable baggie and add chicken breasts. Marinate in the refrigerator at least 1 hour to overnight.

Preheat an outdoor grill for medium heat and lightly oil the grate.

Place chicken on the preheated grill and cook until no longer pink in the center and juices run clear, about 5 minutes per side.
