Preheat the oven to 400°F (200°C).
Pat the pork tenderloin dry with paper towels and season all sides with salt and black pepper.
Heat olive oil in a large oven-proof skillet over medium-high heat until shimmering.
Sear the pork tenderloin for 1 to 2 minutes per side until a golden-brown crust has formed on all surfaces.
In a small mixing bowl, whisk together the honey, minced garlic, soy sauce, and apple cider vinegar.
Pour the honey garlic mixture over the pork in the skillet, ensuring the meat is well-coated.
Transfer the skillet to the oven and roast for 12 to 15 minutes, or until the internal temperature reaches 145°F (63°C).
Remove the pork from the skillet and transfer to a cutting board; let it rest for 5 to 7 minutes.
Place the skillet back on the stovetop over medium heat and simmer the remaining sauce for 3 minutes until it thickens into a syrupy glaze.
Slice the pork into 1-inch medallions and serve immediately with the reduced glaze spooned over the top.
