How to Make It
Heat the olive oil in a large pot. Add the onion and peppers and cook, stirring occasionally, over moderately high heat until the onions are soft and translucent, about 5 to 7 minutes. Add the jalapeño and garlic and cook for 1 minute. Add the chili powder, cumin, cocoa, oregano, paprika, cayenne, red pepper, salt and a few turns of black pepper; cook until fragrant, about 1 to 2 minutes.
Stir in the tomatoes and the vegetable broth and bring to a boil. Add the beans, reduce heat and simmer for 20 minutes.
Meanwhile, heat 1/2 inch of vegetable oil in a skillet over moderate heat until shimmering. Fry the tortilla strips in batches for 3 minutes, until crispy. Transfer to a paper towel and immediately sprinkle with salt and squeeze with lime.
When the soup is finished simmering, gently stir in the corn.
Ladle into bowls and serve with tortilla strips, lime wedges, diced avocado, sour cream, fresh cilantro and shredded Monterey jack or crumbled queso fresco.
