1. Preheat the oven to 350 degrees F. Warm a large pot for a few minutes over medium heat and add a tbsp of oil. Season the chicken with salt and pepper on both sides and add it to the pot, skin side down. Brown the chicken well on both sides (a few minutes per side), then transfer to a baking sheet and into the oven. Bake the chicken until it registers 165 degrees internally, 25-30 min.
2. In the same pot, combine the onion, poblanos, bell peppers, jalapeño, and garlic with a big pinch of salt. Cook the vegetables, stirring occasionally, until the onions are translucent. Next, stir in the cumin, coriander, chili powder and oregano; continue stirring for 1 minute. Add the tomato paste and stir for 2 minutes.
3. Add the remaining ingredients to the pot along with a huge pinch of salt. Stir well, bring to a boil, and simmer for 20 minutes or so. When the chicken is done and cool enough to handle, remove the skin, shred the meat and stir it into the soup. Taste and adjust the seasoning if necessary. Serve with the suggested garnishes at the table.

Tortilla Strips

1. Heat a shallow layer of oil (about 1/2 inch) in a large pan over medium-high heat. Cut the tortillas into strips. To test if the oil is ready, put a little piece of tortilla in the pan. The oil should bubble up rapidly around it, cooking it to a golden brown in a minute or so.
2. Crisp the tortillas in batches (don’t overcrowd the pan), removing them with a slotted spoon or spider strainer when crispy and golden brown. Transfer them to a paper towel-lined plate and sprinkle with salt before moving on to the next batch.
