Make this quick soup vegetarian by substituting vegetable broth for the chicken broth.
In a 4-quart Dutch oven heat olive oil over medium-high heat. Cook and stir the onion, carrot, and garlic in hot oil about 3 minutes or until onion is tender. Stir in the broth, undrained tomatoes, water, uncooked rice, and Italian seasoning.
Bring to boiling; reduce heat. Simmer, covered, about 20 minutes or until rice is tender. Stir in the spinach, beans, zucchini, and pepper. Cook, covered, for 5 minutes more. If desired, sprinkle each serving with Parmesan cheese.
