For added flavor, consider sautéing minced garlic with the onions and vegetables at the beginning. Adjust the consistency of the soup by adding more chicken broth or water if it becomes too thick. You can sneak in other vegetables like spinach, peas, or corn for a nutritional boost. To store the soup, allow it to cool completely before transferring it to an airtight container. It can be kept in the refrigerator for up to three days or frozen for up to three months. When reheating, ensure to heat it thoroughly on the stove or in the microwave.
