Start by heating a tablespoon of oil in a large pot over medium heat. Add diced onions and minced garlic, cooking until translucent and fragrant, around 3-4 minutes.

Pour in the canned tomatoes and chicken broth, stirring well to mix. Allow to warm up for about 5 minutes.

Sprinkle in the taco seasoning, adjusting to your taste. Let this simmer for an additional 5 minutes.

Introduce your shredded chicken breast to the pot, stirring until evenly distributed. Let it heat through for about 3-4 minutes.

Bring the soup to a gentle boil, then reduce the heat and let it simmer for 10 minutes.

Ladle the hot soup into bowls, inviting everyone to customize with toppings like tortilla strips, avocado, cheese, and fresh cilantro.

For a zesty kick, squeeze fresh lime juice over the soup before serving!
