Preheat your oven to 400°F (200°C) and line a baking sheet with parchment paper.
Peel the sweet potato and cut it into 1/2-inch cubes.
Toss the sweet potato cubes on the baking sheet with half of the olive oil, the smoked paprika, and a pinch of sea salt.
Roast the sweet potatoes for 20-25 minutes until they are tender and slightly caramelized on the edges.
While the potatoes roast, season the chicken breast with garlic powder, sea salt, and black pepper.
Heat the remaining olive oil in a skillet over medium heat and cook the chicken for 6-7 minutes per side until the internal temperature reaches 165°F.
Remove the chicken from the pan, let it rest for 5 minutes, then shred it thoroughly using two forks.
In a large mixing bowl, massage the chopped kale with the lemon juice until the leaves become vibrant green and tender.
Add the roasted sweet potatoes and shredded chicken to the kale bowl, toss everything together until well combined, and serve warm.
