For the soup, stack the corn tortillas on top of each other. Cut pile in half. Cut each stack into ¼-inch thick strips, widthwise.

In a large Dutch oven or heavy-duty soup pot, heat oil over medium heat. Add onion, green onions, cilantro, garlic, oregano, cumin, chili powder, brown sugar, paprika. Sauté for 8-10 minutes or until onions are translucent and tender. Add corn tortilla strips and sauté for another two minutes or until softened.

Add tomatoes and broth and bring to a boil. Reduce to a simmer and cook, uncovered for 45 minutes, maintaining a steady simmer. (Tortilla strips should be melted into the broth by this point.) Add chicken and cook for another 5 minutes. Remove from heat and add lime juice. Taste and add a generous grind of freshly ground black pepper and salt as needed.

Serve soup topped with tortilla strips, sliced green onion, chopped, fresh cilantro, diced avocado and lime wedges.

For the crispy tortilla strips, preheat oven to 400˚F. Line a sheet pan with foil for easy clean up.

Stack and cut tortillas in the same way as directed above in the soup recipe. Place strips on prepared sheet pan and drizzle with 1 tablespoon of olive oil. Sprinkle with ½ teaspoon kosher salt and toss lightly with your hands until all strips are coated with oil. Spread out, as much as possible, to a single layer. Bake for 10 minutes then remove from oven and toss with a spatula. Redistribute to an even layer and return to oven. Repeat until golden and crisp, a total baking time of 20-30 minutes.
