Preheat your oven to 400°F (200°C) and line a large rimmed baking sheet with parchment paper for easy cleanup.
Peel the sweet potato and dice it into 1/2-inch cubes, then cut the chicken breast into similar bite-sized pieces.
In a small mixing bowl, whisk together the extra virgin olive oil, honey, lime juice, sea salt, black pepper, and garlic powder until well combined.
Place the chicken and sweet potato cubes in a large bowl, pour the prepared glaze over them, and toss thoroughly to ensure every piece is coated.
Spread the mixture in a single layer on the prepared baking sheet and roast for 22-25 minutes, or until the chicken is cooked through and the potatoes are tender and caramelized.
While the sheet pan is roasting, steam the broccoli florets for 4-5 minutes until they are bright green and tender-crisp.
Plate the steamed broccoli and top with the roasted chicken and sweet potato mixture, then garnish with chopped fresh cilantro before serving.
