Preheat your oven to 400°F and line a large baking sheet with parchment paper for easy cleanup.
Peel and dice the sweet potato into 1-inch cubes, then toss them on the baking sheet with half of the olive oil, sea salt, and black pepper.
Roast the sweet potatoes for 20-25 minutes, or until they are fork-tender and show slightly caramelized edges.
While the potatoes roast, season the chicken breast evenly with the garlic powder and the remaining sea salt and pepper.
Heat the remaining olive oil in a non-stick skillet over medium-high heat and sear the chicken for 6-7 minutes per side until the internal temperature reaches 165°F.
Steam the broccoli florets in a small pot with a splash of water for 4-5 minutes until they are bright green and tender-crisp.
In a small mixing bowl, whisk together the honey and lime juice until smooth to create the glaze.
Slice the cooked chicken and arrange it on a plate with the roasted sweet potatoes and steamed broccoli.
Drizzle the honey-lime glaze over the chicken and potatoes, then garnish with chopped fresh cilantro before serving.
