Preheat your oven to 400°F (200°C) and line a small baking sheet with parchment paper.
In a small bowl, whisk together the honey, tamari, hoisin sauce, minced garlic, ginger, and Chinese five-spice powder to create the glaze.
Season the pork tenderloin with sea salt and black pepper, then place it on the baking sheet.
Brush half of the honey-garlic glaze over the pork and roast for 15 minutes.
While the pork is roasting, halve the baby bok choy and toss with the toasted sesame oil.
Remove the pork from the oven, brush with the remaining glaze, and arrange the bok choy around the meat on the tray.
Return to the oven and roast for another 8-10 minutes, or until the pork reaches an internal temperature of 145°F and the bok choy is tender-crisp.
Allow the pork to rest for 5 minutes before slicing into medallions.
Serve the sliced pork and bok choy over the warm jasmine rice, drizzling any remaining pan juices over the top.
