Heat olive oil in a large saucepan over medium heat. Add garlic, leek, and salt. Cook, stirring occasionally, for 3 minutes. Add carrot, celery, zucchini, cannellini beans, and cups chicken broth. Simmer, covered, until the vegetables are tender, about 15 minutes. Add shredded pork cutlets and cook 5 minutes more. Season to taste with more salt and freshly ground pepper.
