Preheat your oven to 400°F and line a baking sheet with parchment paper.
Dice the sweet potato into 1/2-inch cubes and trim the woody ends from the asparagus spears.
Toss the sweet potato cubes with 0.25 tbsp of olive oil, a pinch of salt, and a pinch of pepper, then roast for 15 minutes.
Season the pork tenderloin evenly with the dried thyme, remaining sea salt, and black pepper.
In a small bowl, whisk together the honey, balsamic vinegar, and minced garlic to create the glaze.
Heat the remaining 0.5 tbsp of olive oil in a large oven-safe skillet over medium-high heat and sear the pork for 2 minutes per side until browned.
Pour the honey-balsamic glaze over the pork in the skillet, coating it thoroughly.
Place the asparagus on the baking sheet with the sweet potatoes and put the pork skillet in the oven.
Roast everything for 10-12 minutes until the pork reaches an internal temperature of 145°F.
Allow the pork to rest for 5 minutes before slicing and serving with the roasted vegetables and pan glaze.
