Add the tomatoes, dry onion soup mix, and low-sodium vegetable broth to a large soup pot or dutch oven and mix well.
Add the remaining vegetables to the pot, gently stir, and make sure everything is well combined. Let the soup come to a boil.
Once the soup comes to a boil, reduce the heat to medium-low, taste and season with salt and pepper, cover the pot with a lid, and let the soup simmer for 60-90 minutes or until the veggies are tender.
