Preheat the oven to 400°F and line a large baking sheet with parchment paper.
Peel and dice the sweet potato into 1-inch cubes, then place them on the baking sheet.
Drizzle the sweet potatoes with olive oil, sea salt, and black pepper, tossing to coat evenly.
Roast the sweet potatoes for 15 minutes.
While roasting, dice the chicken breast into 1-inch pieces and whisk together the honey, lime juice, sesame oil, and garlic powder in a small bowl.
Add the chicken and broccoli florets to the baking sheet with the potatoes.
Roast for an additional 12 to 15 minutes until the chicken is cooked through and the potatoes are tender.
Remove from the oven, drizzle the honey-lime glaze over the mixture, and toss well before garnishing with fresh cilantro.
