Place chicken tenders and marinade ingredients in a resealable, leak-proof bag. Marinate for 2 hours - overnight in refrigerator.
Remove chicken from marinade, and pat dry chicken tenders with paper towels. Discard all excess marinade.
Preheat grill pan. Once pan is hot, add chicken tenders. Reduce heat to medium and sear chicken on both sides for 5 minutes per side, or until meat thermometer inserted into the thickest part reads 165°F.
