Heat the avocado oil in a large heavy-bottomed pot over medium heat.
Add the diced onion, bell pepper, and minced garlic, sautéing until the vegetables are softened and fragrant.
Stir in the chili powder, cumin, smoked paprika, sea salt, and black pepper to toast the spices for 1 minute.
Pour in the chicken bone broth and diced tomatoes, then add the raw chicken breasts and drained black beans.
Bring the liquid to a gentle boil, then reduce heat and simmer for 20 minutes until the chicken is tender and cooked through.
While the soup simmers, slice corn tortillas into thin strips and bake at 375°F for 10 minutes until golden and crispy.
Remove the chicken from the pot, shred it using two forks on a cutting board, and return the meat to the soup.
Stir in the full-fat coconut milk and the juice of one lime to create a creamy, bright finish.
Ladle the soup into bowls and top with sliced avocado, fresh cilantro, crispy tortilla strips, and extra lime wedges.
