Preheat oven to 400°F (200°C) and line a large baking sheet with parchment paper.
Peel and dice the sweet potato into 1/2-inch cubes and cut the chicken breast into bite-sized pieces.
In a small bowl, whisk together the olive oil, honey, lime juice, garlic powder, and smoked paprika until well combined.
Place the chicken, sweet potato cubes, and broccoli florets on the prepared baking sheet.
Drizzle the honey-lime mixture over the ingredients and season with sea salt and black pepper.
Toss everything together until evenly coated, then spread into a single layer.
Roast for 20-25 minutes, or until the chicken is cooked through and the sweet potatoes are tender and slightly caramelized.
Garnish with freshly chopped cilantro before serving.
