Place your ham hock in the middle of your Instant Pot. (you could add diced leftover ham too but a ham hock is delicious)
Add all vegetables and cup of uncooked pearled barley around ham hock, then pour broth in.
Close your lid and steam valve and set to high pressure for 30 minutes. Then do a quick release when done.
Lift lid and remove ham hock. On a cutting board remove all bones and fat, discard those. Dice your meat up into bite size pieces or shred. Put meat back into your Instant Pot and stir.
Serve!I did not add any salt or seasonings because the flavors in the ham hock permeated the soup and gave it a wonderful flavor, it didn't need anything else at all as far as we were concerned but you could add salt and pepper to taste.
