In a large saucepan, combine the salsa, tomato juice, rice, onion, Italian seasoning, bouillon, garlic, pepper and 2 cups water. Bring to boil; reduce heat. Cover and simmer for 10 minutes. Meanwhile, place frozen vegetables in a colander. Run cold water over vegetables until thawed. Stir into rice mixture. Return to boiling; reduce heat. Cover and simmer for 5 to 10 minutes, or until rice and vegetables are tender. Top each serving with cheese, if desired.
