01 -  Preheat oven to 425°F. Line a baking sheet with parchment paper or lightly grease it for roasting. 
 02 -  Pat pork tenderloin dry. Season evenly with kosher salt and black pepper. Heat olive oil in a large ovenproof skillet over medium-high heat. Sear pork on all sides until golden brown, about 2 to 3 minutes per side. Remove skillet from heat. 
 03 -  In a small mixing bowl, whisk together maple syrup, Dijon mustard, whole-grain mustard, apple cider vinegar, minced garlic, and dried thyme until well combined. 
 04 -  Brush half of the maple-Dijon glaze over the seared pork tenderloin, coating all surfaces. 
 05 -  Toss apple wedges with melted unsalted butter, ground cinnamon, brown sugar, and a pinch of salt until evenly coated. 
 06 -  Arrange prepared apple wedges around the glazed pork in the skillet, or transfer both pork and apples to a lined baking sheet. 
 07 -  Transfer the skillet or baking sheet to the preheated oven. Roast for 18 to 22 minutes, or until the pork reaches an internal temperature of 145°F. Stir apples halfway through roasting for even caramelization. 
 08 -  Remove pork from the oven and transfer to a cutting board. Rest for 5 minutes to retain juices. 
 09 -  Brush pork with the remaining glaze. Slice and serve alongside the roasted apples.
