Prepare The Soup Base: Heat olive oil in a large pot over medium heat. Add chopped onions, minced garlic, and diced jalapeno pepper. Saute until the onions turn translucent and the peppers soften about 5 minutes.
Spice Infusion: Stir in ground cumin, chilli powder, and Chicken bouillon powder. Let the spices bloom for about a minute, releasing their flavors into the mix.
Chicken And Tomatoes: Add the diced chicken breasts to the pot. Cook and stir until the chicken turns white on the outside, for about 5 minutes. Pour in the crushed tomatoes and chicken broth. Bring the mixture to a boil, then reduce the heat to low and let it simmer for 15-20 minutes, allowing the flavours to meld.
Adding Beans, Corn, And Herbs: Stir in the drained and rinsed black beans, corn, and 3/4 of the chopped cilantro. Let the soup simmer for an additional 10 minutes.
Citrus Infusion: Squeeze the juice of one lime into the soup. Season with salt to taste, adjusting as needed.
Prepare the Tortilla Strips: While the soup is simmering, preheat the oven to 375°F (190°C). Brush both sides of the corn tortillas with olive oil. Stack the tortillas and cut them into strips. Place the strips on a baking sheet and bake for about 10-12 minutes or until golden and crispy.
Serve And Garnish: Ladle the hot soup into bowls. Top each serving with diced avocado, a sprinkle of the remaining chopped cilantro, and a few homemade tortilla strips. Serve with lime wedges on the side.
