01 - In a large skillet over medium-high heat, add ground beef. Cook, breaking up with a spoon, until browned and cooked through, about 5 minutes. Drain excess fat if needed.
02 - Add diced onion, bell peppers, and garlic. Sauté for 4-5 minutes until vegetables are softened.
03 - Stir in rice, diced tomatoes with juice, broth, oregano, basil, smoked paprika, salt, pepper, and red pepper flakes. Mix well.
04 - Bring to a gentle boil, then reduce heat to low. Cover and simmer for 20 minutes until rice is tender and most liquid is absorbed. Stir occasionally to prevent sticking.
05 - Uncover, sprinkle cheese evenly over the top, and cover again for 2-3 minutes, until cheese melts.
06 - Serve hot, garnished with fresh parsley if desired.
