Grilled Teriyaki Pork Tenderloin

As many know, i couldn't live without pork! At least twice a week i need to cook some part of Mr. Oink to fulfill my needs! And tenderloin is definitely the easiest way to do it. And the size of a tenderloin is usually perfect for my family of 3.
Since these last few weeks have been so hot, I have tried to do most the cooking outside on the grill, I might get a little hot but the house stays cool and our electric bill stays down... So, anyway you think, I'm winning! Oh yes, forgot to mention, it also tastes really good!!!!!

Ingredients:

1 pork tenderloin ( they are usually between 1 1/4 lb to 1 1/2 lb)

juice of 1 orange

1 cup teriyaki sauce

1/3 cup  soy sauce

1/3 cup rice vinegar

1 teaspoon salt

2 teaspoons pepper

1 large(gallon) ziplock bag

Put all ingredients but pork in ziplock back and mix it well. Add pork and let it marinate for a minimum of 3 hours and up to 24 hours in the refrigerator.

Remove pork from refrigerator 1 hour before cooking. Preheat the grill to its highest setting. Place pork on grill and lower temperature to medium. Save the bag with the marinate. Close the grill cover and cook for 25 minutes per pound, turning the pork after 15 minutes and brushing some of the marinate on the pork as you turn it.

I placed a couple of peach halves on grill with pork and brushed the same marinate on them, and cooked for 10 minutes per side. Very good.
