Preheat your oven to 400°F and line a large baking sheet with parchment paper.
Peel and dice the sweet potato into 1/2-inch cubes, then toss them directly on the baking sheet with half of the olive oil and a pinch of sea salt.
Roast the sweet potatoes for 20-25 minutes, tossing halfway through, until they are tender and the edges are golden brown.
While the potatoes roast, heat the remaining olive oil in a large non-stick skillet over medium-high heat.
Add the diced red onion and bell pepper to the skillet, sautéing for 3-4 minutes until the vegetables begin to soften.
Add the ground turkey to the skillet, breaking it apart with a wooden spoon or spatula, and cook until no longer pink.
Stir in the smoked paprika, cumin, garlic powder, sea salt, and black pepper, ensuring the turkey is evenly coated in the spices.
Add the chopped kale to the skillet and cook for an additional 2 minutes until the leaves are just wilted and bright green.
Remove the roasted sweet potatoes from the oven and divide them into serving bowls.
Top the sweet potatoes with the smoky turkey and vegetable mixture and serve immediately.
