01 - Preheat oven to 400°F. Lightly grease a 9x13-inch baking dish and set aside.
02 - Heat olive oil in a large skillet over medium heat. Add the ground turkey and cook for 5 to 7 minutes, breaking it apart with a wooden spoon until fully browned and no pink remains.
03 - Add the diced red onion, red bell pepper, and minced garlic to the skillet. Sauté for 3 to 4 minutes until the vegetables are softened and fragrant.
04 - Stir in the diced sweet potatoes and cook for an additional 3 minutes, allowing them to begin softening and picking up flavor from the spices.
05 - Add the drained black beans, diced tomatoes with their juice, ground cumin, smoked paprika, chili powder, salt, and black pepper. Stir thoroughly to combine all ingredients evenly.
06 - Reduce the heat to medium-low, cover the skillet, and simmer for 10 minutes. This allows the spices to meld and the sweet potatoes to begin tenderizing.
07 - Pour the entire mixture into the prepared 9x13-inch baking dish, spreading it out into an even layer.
08 - Cover the baking dish tightly with aluminum foil and bake for 20 minutes to continue cooking the sweet potatoes through.
09 - Remove the foil and sprinkle the shredded cheese evenly across the top. Return to the oven uncovered and bake for another 10 minutes, or until the sweet potatoes are fork-tender and the cheese is melted and bubbly.
10 - Remove from the oven and garnish with chopped fresh cilantro or parsley if desired. Serve hot.
