Slice the pork tenderloin into 1-inch thick medallions and season both sides evenly with the five-spice powder, sea salt, and black pepper.
In a medium skillet over medium heat, add the olive oil and carrot coins with two tablespoons of water; cover and steam for 5-6 minutes until tender-crisp.
Remove the lid from the carrots, then add the honey, minced ginger, and half of the tamari, tossing constantly until the liquid reduces and coats the carrots in a glossy sheen.
In a separate cast-iron or heavy skillet, heat the sesame oil over medium-high heat until shimmering.
Place the pork medallions in the hot skillet and sear for 3-4 minutes per side until a dark, fragrant crust forms and the internal temperature reaches 145°F.
Pour the remaining tamari over the pork in the last 30 seconds of cooking, swirling the pan to coat each medallion.
Plate the charred pork medallions alongside the glazed carrots and garnish with chopped fresh cilantro.
