01 - Preheat the 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 evenly browned and no pink remains.
03 - Add the diced onion, red bell pepper, and minced garlic to the skillet. Sauté for 3 to 4 minutes until the vegetables have softened and become fragrant.
04 - Stir in the diced sweet potatoes and cook for an additional 3 minutes, allowing them to lightly coat in the seasonings and begin softening at the edges.
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 let the mixture simmer for 10 minutes. This allows the flavors 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. This steams the sweet potatoes, helping them cook through evenly.
09 - Remove the foil and sprinkle the shredded cheddar or Monterey Jack 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 let rest for 5 minutes. Garnish with chopped fresh cilantro or parsley if desired. Serve hot.
