This was REALLY good! I used plain frozen chicken and this instant pot recipe: https://s.samsungfood.com/NgqU1, then shredded it and mixed it in the sauce from this recipe, minus the cream cheese.
Once done, I made refried beans in the instant pot from here: https://app.samsungfood.com/recipes/101cac63bbc7d4e77cc352b809c19a950f70745b8ae?utm_source=android&utm_medium=shared-link&utm_campaign=whisk-recipe (seen in the bowl with Jalapeño strips, guac, cilantro and cotija in the image). I put strips of cream cheese, the shredded chicken and sauce (minus the cream cheese) from this recipe, and Cheddar cheese in them and fried them.
I made a couple with cream cheese strips and julienned Jalapeños and they were really good, too.
FWIW, 2 rather large thin cut chicken breasts from Costco made enough for about 20.
