Set the cream cheese out on your counter 1.5-2 hours before you begin cooking. Alternatively, microwave on a glass plate for 20-30 seconds.
Place the four chicken breasts into the liner of your Instant Pot
In a small bowl, mix together the chicken broth and the diced tomatoes with green chilis. Add the chili powder, garlic powder, cumin, ranch and oregano and stir to combine.
Pour the broth and tomato mixture evenly over the chicken breasts.
Cook on high pressure for 20 minutes for frozen breasts, or 10 minutes for thawed chicken breasts. After the cooking time is up, allow the cooker to release the pressure naturally.
Once the pressure has released and the pin on the lid of your Instant Pot has dropped, carefully remove the lid and turn the pot to the sauté mode on low heat.
Add in the cream cheese and allow it to melt, breaking up the block into smaller pieces.
Next, pour in the corn and beans and stir together until they are both warm and the cream cheese has melted, making sure the soup doesn't boil. If it begins to boil, just turn the heat off.
Finally, add the tortilla strips and avocado, and salt to taste.
Pile high with toppings and enjoy!
