Combine all ingredients EXCEPT the frozen peas into the pot of a 6 or 8 Quart instant pot. Stir to distribute. Secure the lid and cook on high pressure for 7 minutes.
After 7 minutes has elapsed, turn the instant pot off and let it naturally release for 10-15 minutes. Basically that means turn it off and don't touch anything else.
After 10-15 minutes, manually release. After the pressure has been released, oped the lid and add the frozen peas and stir. The peas will warm up in a few minutes with the heat of the stew.
Let cool a bit before serving. This stays HOT for a while.
Enjoy with a big crusty piece of bread.
