Use a tomato soup base or make your own with veggie broth and fire roasted diced tomatoes.
Add the following to the broth and simmer until veggies are tender:
diced zucchini, diced onion, corn, your favorite canned beans rinsed (black or pinto work well), diced mild pepper such as aneheim or poblano. You can add shredded chicken for a meatier version.
While the soup is simmering prepare your toppings. Here are some we like to use: chopped cilantro, shredded cheese, sour cream, diced avocado or guacamole, pepitas, lime and tortilla strips (slice tortillas and crisp them in a pan, or tortilla chips or fritos work too!)
When the veggies are tender, build your own soup by adding your toppings. Don’t forget the tortilla strips!
