Preheat your oven to 400°F and line a large baking sheet with parchment paper.
Dice the chicken breast and sweet potato into uniform 1-inch cubes for even cooking.
In a large bowl, toss the chicken and sweet potato cubes with olive oil, chili powder, cumin, sea salt, and black pepper until well coated.
Spread the mixture in a single layer on the prepared baking sheet and roast for 20 minutes.
Rinse and drain the black beans, then add them to the baking sheet, tossing gently with the chicken and potatoes.
Roast for an additional 5 minutes until the chicken is cooked through and the potatoes are tender.
While the tray finishes roasting, place the chopped kale in a serving bowl and drizzle with lime juice, massaging it with your hands for 1 minute to soften the leaves.
Top the massaged kale with the roasted chicken, sweet potatoes, and warm black beans before serving.
