Preheat your oven to 400°F (200°C).
Prepare the quinoa by simmering in water or low-sodium broth until all liquid is absorbed and the grain is fluffy.
Trim the woody ends off the asparagus spears.
Wrap each asparagus spear tightly with a slice of bacon, or bundle two spears together per slice if preferred.
Place the bacon-wrapped asparagus on a baking sheet lined with parchment paper and roast for 15-18 minutes until the bacon is crisp.
Season the pork tenderloin generously with sea salt, cracked black pepper, and garlic powder.
Heat the olive oil in a cast-iron or oven-safe skillet over medium-high heat.
Sear the pork tenderloin on all sides for about 2 minutes per side until a deep golden crust forms.
Transfer the skillet to the oven and roast for 10-12 minutes or until the internal temperature reaches 145°F.
Remove the pork from the oven and let it rest for at least 5 minutes before slicing into medallions.
Serve the sliced pork alongside the crispy bacon-wrapped asparagus and the warm quinoa.
