1. Preheat the oven to 400°F and line a large baking sheet with parchment paper.
2. Peel the sweet potato and cut it into 1/2-inch cubes, then toss with half the olive oil and a pinch of sea salt and black pepper.
3. Roast the sweet potato cubes for 20-25 minutes until they are tender and caramelized.
4. While the potatoes roast, heat the remaining olive oil in a large skillet over medium-high heat.
5. Add the ground turkey to the skillet, breaking it into small crumbles, and cook until browned and no longer pink.
6. Season the turkey with the garlic powder, ground cumin, onion powder, and the remaining sea salt and black pepper.
7. Stir in the diced red bell pepper and sauté for 3-5 minutes until the pepper is tender-crisp.
8. Add the fresh baby spinach to the skillet and toss for 1-2 minutes until the leaves are just wilted.
9. Divide the roasted sweet potatoes into bowls and top with the savory turkey and vegetable mixture.
