Marinated and Grilled Pork Tenderloin

This is a photo I got from Paula Deen's site of her grilled pork tenderloin.  It is one of our favorites, and so e.a.s.y. to do.  Did I say 'easy'? Because it is, and oh sooo good!  Paula has such pretty dishes, doesn't she!

This is our version of Paula's recipe. 
Ingredients:
Marinade:
--1/2 cup soy sauce
--Juice of 2 oranges (you can squeeze fresh, or use 1 cup orange juice.  I like Simply Orange.  1 orange = 1/2 cup juice)
--Juice of 1 lime (which is about 1 1/3 Tablespoons)
--1 Tablespoon Dijon mustard
--1 teaspoon ground ginger
--1 clove garlic, or 1 teaspoon chopped garlic from the jar
--1 green onion, chopped
--1 pork tenderloin from Costco
--Olive oil for brushing

Directions:
--Combine marinade ingredients in a cup and stir to combine.  Place tenderloin in large ziploc plastic bag and pour marinade over.  Seal and place in refrigerator overnight or at least 2-4 hours.  I've done it for 2 hours and it's fine.  But if you want to prepare it the night before or earlier during the day you can.
--Preheat outdoor grill or oven to 350*
--Brush grill with olive oil.
--Remove tenderloin from bag and let marinade drip back into bag.  Place on grill and lightly brush with olive oil.
--Grill until done for about 12-15 minutes on each side.  Or roast in oven for 35-40 minutes.  Remove to platter and cover lightly with foil to let rest for about 10 minutes while you plate up the rest of your dinner.  Slice into 1-2 inch slices.
--While meat is grilling, place marinade in a saucepan and bring to a boil.  Let simmer till it's reduced to about 3-4 tablespoons.  You can serve a little over the meat, but we just like it plain.  It is so juicy and good!
