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, cooking until the onion is translucent, about 3-4 minutes.
Stir in the diced tomatoes, uncooked rice, broth, chopped bell peppers, Italian seasoning, salt, and pepper. Bring the mixture to a boil.
Reduce the heat to low, cover, and simmer for 20-25 minutes, or until the rice is tender and has absorbed most of the liquid.
Remove the skillet from heat and sprinkle the shredded cheese on top. Cover for a few minutes until the cheese melts.
Serve hot, garnished with fresh herbs if desired.
