Preheat your oven to 400°F (200°C) and line a large baking sheet with parchment paper.
Peel and cube the sweet potatoes into 1/2-inch pieces, then toss them on the baking sheet with half the olive oil, smoked paprika, and a pinch of sea salt.
Roast the sweet potatoes for 20-25 minutes, flipping halfway through, until they are tender and caramelized on the edges.
Season the chicken breast with garlic powder, black pepper, and the remaining sea salt, then pan-sear in a non-stick skillet over medium-high heat for 6-7 minutes per side.
While the chicken rests, place the chopped kale in a bowl with the lemon juice and the remaining olive oil, massaging the leaves with your hands until they soften and turn bright green.
Rinse and drain the black beans, then warm them briefly in the microwave or a small saucepan.
Slice the chicken into strips and assemble your bowl by layering the massaged kale, warm black beans, roasted sweet potatoes, and the sliced chicken.
