In a saucepan over medium heat, combine diced peaches, honey, soy sauce, apple cider vinegar, ginger, garlic, salt, and pepper.

Cook for about 10 minutes, stirring occasionally, until the peaches are soft and the mixture thickens slightly.

Remove from heat and let cool slightly.

Preheat the oven to 400°F (200°C).

Heat a skillet over medium-high heat and sear the pork tenderloin on all sides until browned, about 5 minutes.

Transfer the pork to a baking dish and brush generously with the peach glaze.

Bake in the preheated oven for 20 minutes, or until the internal temperature reaches 145°F (63°C).

Remove the pork from the oven and let it rest for 5 minutes before slicing.

Serve slices drizzled with additional peach glaze if desired.
