Heat the olive oil in a large dutch oven over medium-high heat. Add the beef, sprinkle with the Italian seasoning and cook, breaking up the meat into small pieces with a wooden spoon, until browned, 4 to 6 minutes.  Add the onion and bell peppers and cook, stirring, until they start to soften, 4 to 6 minutes. Stir in the garlic, salt and pepper and cook for 30 seconds.  Stir in the rice, then add the broth, tomato puree and diced tomatoes. Stir to combine. Bring the soup to a simmer, then reduce the heat to low, cover and cook until the rice is tender, about 25 minutes. Stir in the Worcestershire sauce. Ladle the soup into bowls and top with the cheese and parsley.
