Preheat your oven to 400°F and line a large baking sheet with parchment paper for easy cleanup.
Peel and cube the sweet potato into half-inch pieces and cut the chicken breast into uniform bite-sized chunks.
In a large mixing bowl, toss the sweet potato and chicken with 0.5 tbsp of the olive oil, sea salt, black pepper, and garlic powder.
Spread the chicken and potato mixture in a single layer on the baking sheet and roast for 20-25 minutes until the chicken is cooked through and potatoes are tender.
While the tray is in the oven, whisk together the honey, lime juice, and lime zest in a small bowl to create the glaze.
In a skillet over medium heat, sauté the kale with the remaining 0.5 tbsp of olive oil until it is wilted and bright green.
Remove the baking sheet from the oven, drizzle the honey-lime glaze over the hot chicken and potatoes, and toss to coat thoroughly.
Portion the sautéed kale into a bowl and top with the glazed chicken and sweet potato mixture.
