In a large skillet over medium heat, combine Italian sausage and garlic. Cook, stirring frequently until sausage is evenly browned. Drain cooked sausage in a strainer to remove grease.
In a large Dutch oven or stock pot, combine the beef broth, hominy, stewed tomatoes, carrots, beans, and zucchini. Bring to a boil over medium-high heat, and boil for 2 minutes. Reduce heat to low, and add sausage and cilantro; simmer for 15 minutes, or until carrots and zucchini are tender. Season with salt and pepper.
