In a large skillet over medium heat, brown the ground beef with the onion until beef is no longer pink. Drain any excess fat.
Return skillet to heat and add the bell peppers and garlic and cook two minutes more. Stir in diced tomatoes, broth, tomato paste, rice, and salt and pepper.
Bring mixture to a boil, cover and reduce heat. Simmer and let cook until rice is tender, about 18 minutes.
Fluff rice with a fork, top with grated cheese, cover and let rest until cheese has melted. Serve and enjoy!
