In a large skillet, heat the olive oil over medium heat. Add the diced onion and sauté for about 3-4 minutes until softened.
Stir in the minced garlic and cook for an additional minute until fragrant.
Add the ground turkey to the skillet, breaking it up with a spoon. Cook until browned and cooked through, about 5-7 minutes.
Mix in the diced red and green bell peppers, oregano, paprika, salt, and pepper. Cook for another 5 minutes until the peppers are tender.
Stir in the drained diced tomatoes and cooked rice, mixing well to combine. Cook for an additional 2-3 minutes until heated through.
Sprinkle the shredded cheese on top and cover the skillet. Let it sit for 2-3 minutes until the cheese is melted.
Serve warm, garnished with fresh herbs if desired.
