Preheat your oven to 400°F and line a large baking sheet with parchment paper.
Toss the sweet potato cubes and broccoli florets with 1 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 turkey breast into 1-inch thick medallions.
Season both sides of the turkey 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 turkey medallions for 4 to 5 minutes per side until a golden-brown crust forms and the internal temperature reaches 165°F.
Reduce the heat to low and pour the spicy-tangy glaze into the skillet, tossing the turkey to coat evenly for 1 minute.
Remove from heat and serve the glazed turkey medallions immediately alongside the roasted vegetables.
