In a large skillet over medium heat, brown the ground beef or turkey until fully cooked. Drain any excess fat.
Add the diced onion and minced garlic to the skillet and sauté for about 3-4 minutes until the onion is translucent.
Stir in the diced bell peppers and cook for an additional 5 minutes until they begin to soften.
Add the diced tomatoes (with their juice), cooked rice, Italian seasoning, paprika, salt, and pepper. Stir well to combine.
Reduce the heat to low, cover the skillet, and let it simmer for about 10 minutes to allow the flavors to meld.
Remove the lid and sprinkle the shredded cheddar cheese on top. Cover again for 2-3 minutes until the cheese is melted.
Serve hot, garnished with fresh parsley if desired.
