Rinse the turkey liver under running water and pat it with a napkin to remove excess moisture.
Mix teriyaki sauce with dried herbs, pepper, mustard and lemon zest.
Marinate the liver in this marinade for about 15 minutes. You can continue, the taste will be more intense.
Grill on both sides for 7-8 minutes on each side. As soon as the blood stops being released from the liver, it is ready. Do not over-dry, but it should not be raw inside either.
