Preheat your oven to 350°F (175°C).
In a large skillet over medium heat, cook the ground beef or turkey until browned. Drain any excess fat.
Add the diced onion, bell pepper, and minced garlic to the skillet. Sauté for about 5 minutes, until the vegetables are softened.
Stir in the diced tomatoes (with juice), uncooked rice, broth, Italian seasoning, salt, and black pepper. Bring the mixture to a boil.
Reduce the heat to low, cover, and simmer for 20 minutes, or until the rice is cooked and has absorbed most of the liquid.
Transfer the mixture to a greased 9x13 inch baking dish. Sprinkle the shredded cheddar cheese evenly on top.
Bake in the preheated oven for 15-20 minutes, until the cheese is melted and bubbly.
Remove from the oven and let it cool for a few minutes before serving. Garnish with fresh parsley if desired.
