01 - Heat a large skillet over medium-high heat. Add ground beef and cook, breaking up with a spoon, until browned and cooked through, approximately 5 minutes. Drain excess fat if needed.
02 - Add diced onion, bell peppers, and garlic to the skillet. Sauté for 4-5 minutes until vegetables are softened and fragrant.
03 - Stir in rice, diced tomatoes with juice, broth, oregano, basil, smoked paprika, salt, pepper, and red pepper flakes. Mix thoroughly to distribute seasonings evenly.
04 - Bring mixture 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 skillet and sprinkle cheese evenly over the top. Cover again and cook for 2-3 minutes until cheese is melted and bubbly.
06 - Serve hot, garnished with fresh parsley if desired.
