Preheat oven to 350 F and line sheet pan with parchment paper. Set aside.
Remove pork from packaging and pat dry with paper towel. Season all sides with salt and pepper, to taste.
To make glaze: In bowl, whisk apple cider vinegar glaze, mustard, balsamic vinegar, rosemary, sage, thyme and garlic. Add salt and pepper, to taste. In steady stream, slowly add olive oil to emulsify while whisking.
In large skillet, heat oil over medium-high heat. Sear pork loin 2-3 minutes on each side.
Move pork to lined baking sheet and brush on about half the glaze. Roast 30 minutes.
Remove pork from oven and spread sliced apples around pork loin. Brush remaining glaze over pork and apples. Bake 20-30 minutes, or until internal temperature reaches 150 F.
Let pork loin rest at least 10 minutes before slicing.
