Heat 2 tbsp olive oil in a large soup pot over medium heat.
Add diced carrots, zucchini, red pepper, chopped onion, and minced garlic to the pot.
Season with 1 3/4 tsp salt, 1/2 tsp pepper, and 1 tbsp herbes de Provence.
Sauté for about five minutes, until vegetables start to soften.
Add 1 cup dry white wine and cook for a couple of minutes, allowing the alcohol to evaporate.
Stir in the diced tomatoes and cannellini beans.
Add 4 cups chicken stock, increase heat to high, bring to a boil, then reduce heat back to medium.
Stir in the shredded cooked chicken and cook for another 8 minutes or so, until the chicken is heated through and flavors meld.
