01 - Heat a large skillet over medium-high heat. Add the ground beef and cook, breaking it up with a wooden spoon, until browned and cooked through, approximately 5 minutes. Drain excess fat if necessary.
02 - Add the diced onion, bell peppers, and garlic to the skillet. Sauté for 4 to 5 minutes until the vegetables have softened and become fragrant.
03 - Stir in the rice, diced tomatoes with their juice, broth, oregano, basil, smoked paprika, salt, black pepper, and red pepper flakes. Mix thoroughly to distribute all seasonings evenly.
04 - Bring the mixture to a gentle boil, then reduce heat to low. Cover the skillet and simmer for 20 minutes for white rice, or until the rice is tender and most liquid has been absorbed. Stir occasionally to prevent sticking.
05 - Uncover the skillet and sprinkle the shredded cheese evenly over the top. Cover again and cook for 2 to 3 minutes until the cheese has melted completely.
06 - Serve hot while the cheese is still melted. Garnish with fresh parsley if desired.
