Preheat your oven to 400°F (200°C) and grease a 9x13-inch baking dish with olive oil.

In a skillet, heat olive oil over medium heat, add chopped onion, sauté for 3-4 minutes until translucent.

Add ground turkey to the skillet and cook for 5-6 minutes, breaking it apart with a spatula until browned.

Stir in minced garlic, diced red bell pepper, and cubed sweet potatoes. Add smoked paprika, ground cumin, dried thyme, salt, and pepper; cook for another 3-5 minutes.

Transfer the mixture to the greased baking dish, cover tightly with aluminum foil and bake for about 25 minutes.

Remove the foil, sprinkle shredded cheese on top, and bake uncovered for an additional 10-15 minutes until cheese is melted and golden.

Garnish with chopped parsley or cilantro and serve warm.
