1-A cast iron skillet with a lid is highly recommended to make this, but if you don't have one, a heavy bottomed pan (with a lid) will do just fine.

1 1/2 lb pork tenderloin
1+1 Tbsps vegetable oil
1+1 tsps salt
1+1 tsps pepper
2 medium yellow onions, sliced 1/4″ thick
2 medium green apples, cored, peeled and sliced 1/4″ thick
1 cup chicken stock
1/2 cup dry apply cider or unsweetened apple juice
2 Tbsps apple cider vinegar

1. Before adding the oil to brown the tenderloin, preheat your cast iron skillet over medium high heat.
2. Pat the tenderloin dry, and season with 1 tsp salt and 1 tsp pepper. 
3. Add 1 Tbsp of oil to the skillet. Sear the tenderloin until golden brown on all sides and set aside.
4. To the still hot pan, add the remaining Tbsp of oil. Add the apples, onions, and last tsps of salt pepper. Sautee, stirring frequently, until the apples and onions begin to soften and brown.
5. Place the tenderloin on top of the apples and onions. 
6. Add the chicken stock, apple cider and vinegar. Cover and simmer for about 10-15 minutes, or when the internal temperature reaches at least 135F.
7. Remove from heat and let rest, covered, for about 10 minutes. This last step is important - the meat will continue to cook as it cools, the juices spreading evenly throughout but, more importantly, the temperature will continue to rise until it reaches about 145F, the recommended temperature for safe eating.
