Preheat your oven to 400°F and line a large baking sheet with parchment paper.
Peel and dice the sweet potato into 1/2-inch cubes, then toss them with half of the olive oil, garlic powder, and a pinch of sea salt.
Spread the potatoes in a single layer and roast for 20-25 minutes until the edges are golden and caramelized.
While the potatoes roast, whisk together the honey, tamari, and minced garlic in a small bowl to create the glaze.
Season the chicken breast with sea salt and black pepper.
Heat the remaining olive oil in a non-stick skillet over medium-high heat and sear the chicken for 5-6 minutes per side until cooked through.
Steam the broccoli florets in a steamer basket for 4-5 minutes until they are vibrant green and tender.
Reduce the skillet heat to low and pour the honey-garlic glaze over the chicken, simmering for 1-2 minutes until the sauce is thick and glossy.
Plate the chicken with the roasted sweet potatoes and broccoli, drizzling any remaining glaze over the top and finishing with a sprinkle of sesame seeds.
