Preheat your oven to 400°F (200°C) and line a large sheet pan with parchment paper for easy cleanup.
Peel the sweet potato and cut it into 1-inch cubes, then dice the chicken breast into similar bite-sized pieces.
In a small bowl, whisk together the honey, lime juice, olive oil, sea salt, black pepper, and red pepper flakes until well combined.
Place the chicken and sweet potato cubes on the prepared sheet pan, drizzle with half of the honey-lime glaze, and toss to coat evenly.
Roast in the oven for 15 minutes, then remove the pan and add the broccoli florets to the tray.
Drizzle the remaining glaze over the broccoli and toss everything together once more.
Return to the oven for another 10-12 minutes until the chicken is cooked through and the sweet potatoes are tender and caramelized.
Serve immediately while hot and the glaze is glistening.
