Preheat your oven to 400°F and line a baking sheet with parchment paper for easy cleanup.
Peel and dice the sweet potato into 1/2-inch cubes, then toss with half of the olive oil, sea salt, and black pepper.
Spread the sweet potatoes on the baking sheet and roast for 20-25 minutes until they are tender and the edges are caramelized.
While the potatoes roast, whisk together the honey, minced garlic, tamari, and apple cider vinegar in a small bowl to create the glaze.
Season the chicken breast with the remaining sea salt and black pepper on both sides.
Heat the remaining olive oil in a large skillet over medium-high heat and sear the chicken for 5-6 minutes per side until fully cooked.
Reduce the heat to low, pour the honey-garlic glaze into the skillet, and simmer for 2 minutes until the sauce thickens and coats the chicken.
Steam the broccoli florets in a steamer basket for 4-5 minutes until they are bright green and tender-crisp.
Plate the chicken with a generous drizzle of the pan sauce alongside the roasted sweet potatoes and steamed broccoli.
