Roasted Pork Tenderloin with Apples

This recipe is my attempt to flex my chef muscles and show off (however pathetic it may seem).  I had a frozen piece of a pig in the freezer, and about 45 minutes to kill, so I whipped up some pork for dinner. I also got bonus points for using onions and apples from my father-in-law's farm.  +10 

Let's get cooking.

Ingredients:
2 pork tenderloins
2 tbsp. oil (vegetable or olive)
11/2 tsp. salt
1 tbsp. Dijon mustard
1 tbsp. chopped fresh thyme
1/4 tsp. ground black pepper
2 apples, cored & sliced
2 onions, sliced
1 c. chicken stock
1 tbsp. butter

How to make it tasty:
Heat oven to 425 F
Trim loins of silverskin
Pat loins dry
Rub oil over loins, sprinkle with salt, evenly coat
Heat oil in a pan at medium heat
Cook loins til brown on all sides
Put pork on a cutting board or a plate
Add apples & onions to that same pan
Cook for roughly 5 minutes
Meanwhile, rub the pork with mustard, thyme & pepper
Put pork on top of onions & apples & put in the oven
Cook for 10-15 minutes (or until temp is 145-160 F)
Put pork on plate and cover with foil, let sit 10 min.
Place the pan with apples & onions back on stove
Heat on medium
Add chicken stock & use wooden spoon to scrape pan
Bring to a simmer & cook until reduced by half
Add butter & stir until melted
Slice pork in 1" slices
Plate pork slices on a bed of apples & onions 
Drizzle pan sauce on top and serve!

As evidenced below, what once was literally a frozen piece of crap, is now a supremely tasty dish for the family!
