Preheat your oven to 400°F and line a large rimmed baking sheet with parchment paper for easy cleanup.
Peel the sweet potato and dice into uniform 1-inch cubes, then cut the chicken breast into similar bite-sized pieces.
In a large mixing bowl, toss the chicken and sweet potato cubes with olive oil, sea salt, black pepper, and garlic powder until evenly coated.
Spread the mixture onto the prepared baking sheet in a single layer, ensuring pieces are not overcrowded to allow for proper roasting.
Roast in the oven for 20 to 25 minutes, or until the chicken reaches an internal temperature of 165°F and the potatoes are fork-tender.
While the tray is roasting, whisk together the honey and lime juice in a small bowl until the honey is fully dissolved.
Remove the baking sheet from the oven and immediately drizzle the honey-lime glaze over the hot chicken and sweet potatoes.
Toss gently to coat and garnish with fresh chopped cilantro before serving warm.
