Preheat your oven to 400°F (200°C) and line a large baking sheet with parchment paper.
Peel and cube the sweet potato into 1/2-inch pieces, and cut the chicken breast into bite-sized chunks.
In a large bowl, toss the chicken and sweet potato with olive oil, garlic powder, sea salt, and black pepper until evenly coated.
Spread the mixture in a single layer on the baking sheet and roast for 20-25 minutes, or until the chicken is cooked through and the potatoes are tender.
While roasting, whisk together the honey, chili flakes, and apple cider vinegar in a small bowl to create the hot honey glaze.
Place the chopped kale in a serving bowl with a tiny pinch of salt and massage with your hands for 1 minute until it softens and turns dark green.
Remove the chicken and potatoes from the oven, drizzle immediately with the hot honey glaze, and toss to coat.
Serve the glazed chicken and sweet potatoes over the massaged kale base.
