Preheat your oven to 400°F and prepare a baking sheet with parchment paper.
Toss the sweet potato cubes and broccoli florets with 0.5 tbsp of avocado oil and a pinch of sea salt.
Spread the vegetables in a single layer and roast for 20 minutes until the potatoes are tender and the broccoli is slightly charred.
While the vegetables roast, slice the pork tenderloin into 1-inch thick medallions.
Season both sides of the pork medallions with garlic powder, sea salt, and black pepper.
In a small bowl, whisk together the apple cider vinegar, honey, and red pepper flakes to create the glaze.
Heat the remaining 1 tbsp of avocado oil in a large skillet over medium-high heat until shimmering.
Sear the pork medallions for 3 to 4 minutes per side until a golden-brown crust forms and the internal temperature reaches 145°F.
Reduce the heat to low and pour the spicy-tangy glaze into the skillet, tossing the pork to coat evenly for 1 minute.
Remove from heat and serve the glazed pork immediately alongside the roasted vegetables.
