Step 1

Place the chile pieces in a blender and pour in the boiling water. Let soak for 10 minutes, until the chiles are softened, then drain off and discard the water.

Step 2

Cut 1 tomato into quarters and scoop out and discard the core and seeds. Roughly chop the quarters and add to the blender. Core, seed, and finely dice the second tomato and set aside.

Step 3

Add the tomatillos, garlic, and 1⁄2 cup of the finely diced onion and blend until very smooth, scraping down the blender as needed. Do not add any water.

Step 4

Press Sauté (High) on the Instant Pot and heat the oil. Add the diced tomato, the remaining finely diced onion, the carrot, and the Anaheim chile and sauté for about 1 minute until beginning to soften. Add the chile puree and cook, stirring, until the mixture is quite dry and beginning to stick to the pot. Press Cancel.

Step 5

Add the chicken, broth, and salt. Secure the lid and set the Pressure Release to Sealing. Press Soup, then set the cooking time for 20 minutes.

Step 6

When the cooking program is complete, press Cancel. Perform a quick pressure release by moving the Pressure Release to Venting. Open the pot, then transfer the chicken to a plate.

Step 7

Using two forks, shred the chicken into bite-size pieces. Divide the chicken evenly among heated bowls. Top each portion with the tortilla strips, cheese, and diced onion, then ladle the hot broth over the top. Garnish with the avocado and cilantro and serve right away, with the lime wedges.
