In a pot over medium-high heat, add 2 tablespoon olive oil, 3 chopped carrots, 2 chopped celery stalks, and 1 cup chopped yellow onion. Saute the vegetables for 5 minutes, stirring occasionally.
Stir in 3 minced garlic cloves and let cook for 30 seconds.
Now add in 32 oz vegetable broth, 30 oz canned diced tomatoes with the liquid, 3 chopped yellow potatoes, 1 cup chopped green beans, 1 teaspoon Italian seasoning, 1 teaspoon salt and ½ teaspoon ground black pepper. Mix together. Bring the pot to a boil then reduce to let it simmer for 8-10 minutes, or until potatoes, carrots and green beans are softened when poked with a fork.
Once the veggies have softened, add in 1 cup frozen corn and 1 cup frozen peas. Cook for 2 minutes until the corn and peas have heated through. Now the soup is ready to serve.
