1. Heat the olive oil in a large skillet over medium-high heat. Add the ground turkey and cook for 5 to 7 minutes, breaking it up as it cooks, until browned and cooked through.

2. Add the onion and bell peppers to the skillet and cook for 5 minutes until softened. Then, stir in the garlic and cook for 30 seconds, just until fragrant.

3. Stir in the tomato paste and cook for 1 minute. Next, add the diced tomatoes, marinara sauce, Italian seasoning, smoked paprika, salt, and pepper. Simmer the mixture for 6 to 8 minutes, allowing the flavors to meld and the sauce to thicken slightly.

4. Stir in the cooked rice and mix everything together until the rice is heated through.

5. Sprinkle the shredded mozzarella over the top of the mixture, cover the skillet, and cook for 2 to 3 minutes until the cheese is melted and bubbly.

6. Garnish with chopped parsley or basil, if desired, and serve hot.
