In a large pot, warm 1 tablespoon of olive oil over medium heat. Add sausage and cook until browned, then drain and set aside.
Using the same pot, heat the remaining olive oil. Toss in the diced onion and bell peppers, sautéing for about 2-3 minutes until softened. Add minced garlic and cook for another minute.
Pour in the beef broth, diced tomatoes, tomato purée, and Italian herbs. Return the sausage to the pot, stir, and let the soup simmer for about 30 minutes, stirring occasionally.
Stir in the cooked rice and season with salt and pepper.
Ladle into bowls, garnish with fresh parsley and shredded cheese if desired, and enjoy!
