Heat 1½ tablespoons Olive Oil in a large stockpot over medium-high heat. Add 1 Large Sweet Onion, 2 Medium Carrots, 2 Stalks Celery, 2 Cups Button Mushrooms, 2-3 Garlic Cloves, and 1 tablespoon Italian Seasoning, and sauté until soft, about 8-10 minutes.
Stir in 3 Cups Shredded Cooked Chicken, 15 ounces Italian Tomato-Basil Sauce, 7 Cups Chicken Broth, 1 Cup Frozen Corn, and 1 Cup Chopped Green Beans. Bring to a simmer and cook for 15-20 minutes.
Season with Salt and pepper, to taste, then sprinkle with ½ Cup Grated Parmesan Cheese (evenly on each serving) and 2 tablespoons Chopped Fresh Parsley.
Enjoy while hot!
