As the temperature plummets, there's no better way to warm the body than a delicious bowl of soup. This roasted cauliflower and zucchini soup is a real winner. Roasting the vegetables prior to putting them in the soup released a depth of flavor that cannot be achieved with boiling alone. It may seem like a useless extra step, but trust me on this. I guarantee you're gonna thank me.
