Preheat your oven to 400°F (200°C).

In a large skillet, heat the olive oil over medium heat. Add the diced onion and sauté for about 3-4 minutes until translucent.

Add the minced garlic to the skillet and cook for an additional 1 minute until fragrant.

Stir in the ground turkey, paprika, cumin, salt, and black pepper. Cook until the turkey is browned and cooked through, about 7-10 minutes.

In a large mixing bowl, combine the diced sweet potatoes and chopped spinach. Add the cooked turkey mixture and stir until well combined.

Transfer the mixture to a greased 9x13-inch baking dish. Spread it evenly and top with shredded cheddar cheese.

Cover the dish with aluminum foil and bake for 25 minutes. Remove the foil and bake for an additional 10-15 minutes, or until the sweet potatoes are tender and the cheese is bubbly.

Let it cool for a few minutes before serving. Garnish with fresh parsley if desired.
