Heat oil in a large stockpot over medium-high heat.
Add in onions, garlic, carrots, celery, and sauté for about 5 minutes.
Stir in tomatoes, broth, jalapeño, lime juice, and chicken.
Bring to a boil, then lower the heat to low, cover, and simmer until chicken is cooked through about 20 minutes.
Remove your pot from the heat, take the cooked chicken out of the pot, then set the chicken onto a cutting board.
Add coconut milk into your soup pot.
Blend the soup until creamy with an immersion blender, or carefully work in small batches using a conventional blender.
Shred your chicken breast and return it to the soup pot, then stir well to combine everything.
Season with sea salt and pepper to taste if desired.
Ladle your soup into bowls then add toppings of choice.
Enjoy while hot!
