Ingredients

3 teaspoons vegetable oil

2 garlic cloves, minced

1 tablespoon tomato paste

1 cup diced tomatoes with liquid (from a 15-ounce can)

4 teaspoons chili powder

Chicken Soup Base (10 cups broth and 4 cups shredded chicken)

Coarse salt and ground pepper

3 corn tortillas, cut into thin strips

1/2 avocado, thinly sliced

2 ounces cotija cheese, crumbled (1/3 cup)

1/4 cup fresh cilantro leaves

1 scallion, thinly sliced

Lime wedges, for serving

Preparation

Preheat oven to 400 degrees. In a large pot, heat 1 teaspoon oil over medium-high. Add garlic and cook until fragrant, 30 seconds. Add tomato paste, diced tomatoes and liquid, and chili powder and cook until most of liquid is evaporated, 2 to 3 minutes. Add broth and bring to a boil; season with salt and pepper.

Meanwhile, on a rimmed baking sheet, toss tortilla strips with 2 teaspoons oil. Bake until crisp and golden, 8 minutes, tossing halfway through.

Divide chicken, avocado, cheese, cilantro, and scallion among six bowls; top with broth and tortilla strips. Serve with lime wedges.
