Low Carb Parmesan Garlic Encrusted Pork Tenderloin

1 lb pork tenderloin
1 tsp salt
1/2 Tbsp garlic flakes
1/2 Tbsp onion flakes
2 Tbsp grated Parmesan cheese
1 Tbsp olive oil
* serve over spinach or mixed green salad, optional

Preheat oven to 475 degrees.
Get out an ovenproof skillet. If pork tenderloin is in two pieces, take butcher string and tie it together.
Put the salt, garlic flakes, onion flakes, Parmesan cheese, and olive oil in a bowl and stir together until well blended.
Apply this seasoning rub to pork and gently press it on to thoroughly coat the pork.
Set skillet on high heat; when skillet is hot, gently set pork in skillet and sear, turning pork over to brown all sides.
When browned all over, set skillet in preheated oven (do not cover) and bake for 20 to 25 minutes.
Remove skillet and take pork out and set on cutting board - cover loosely with a tent of foil and let rest for 8 to 10 minutes.
Cut into thin slices and serve warm.
Will serve 2 to 4, depending how many side dishes you have.
*You can make a quick hot salad dressing by deglazing the skillet after removing the pork.  Put the skillet over low heat and pour in apple cider vinegar or a good balsamic vinegar, or red or white wine, and stir to remove the browned bits.  Add a little olive oil if you wish.  Then place salad greens on a plate, pour this hot dressing over, and serve the pork tenderloin slices alongside.
