Cut chicken into large chunks so it can break down quicker to shred. Put into pot with all other ingredients on top.
Close lid and steam valve and set to high pressure for 9 minutes with a natural release. Do not touch steam valve to release for 15 minutes.
Open pot, shred chicken, stir all ingredients together and serve on slider buns with a slice of cheese.

Made with Frozen Chicken Breasts
Follow the same directions but make sure your pieces are separated from one another when adding into the pot. You will need to increase the timing from 9 to 12 minutes as well but the rest of the instructions remain the same.
