01 - Preheat the oven to 400°F. Grease a 9×13-inch baking dish and set aside.
02 - In a large skillet over medium heat, cook the ground turkey until browned, breaking it apart with a spoon as it cooks, about 5 to 6 minutes.
03 - Add the diced onion, red bell pepper, and minced garlic to the skillet. Sauté for 3 to 4 minutes until the vegetables are softened.
04 - Stir in the ground cumin, smoked paprika, chili powder, dried oregano, salt, and black pepper. Cook for 1 minute until fragrant.
05 - Add the diced sweet potatoes, rinsed black beans, diced tomatoes with their juices, and chicken broth. Bring to a simmer and cook for 8 to 10 minutes, stirring occasionally.
06 - Transfer the mixture to the prepared baking dish. Cover tightly with foil and bake for 20 minutes.
07 - Remove the foil and sprinkle the shredded cheese evenly over the top. Bake uncovered for another 10 minutes, or until the sweet potatoes are tender and the cheese is melted and bubbly.
08 - Let the bake cool for 5 minutes before serving. Garnish with fresh cilantro and sliced avocado if desired.
