If you’re using a ham hock with ham meat, you don’t have to add the additional cooked diced ham. We used a ham bone that didn't have much meat, so we added the extra diced ham. The saltiness of the broth will vary greatly depending on how well seasoned your chicken broth is and if the ham is salted. Make sure to taste the broth after cooking and adjust seasoning accordingly. Dried beans cook differently too. After several tests, we found that an average cooking time of 1 hour worked best to ensure that different types of dried beans were thoroughly cooked. If you're using larger beans like dried lima beans, they will need an additional 15 minutes cooking time. Instant Pot needs to be a 6-qt size or larger.

Turn Instant Pot on "Sauté”, and add oil. Add the onions and garlic and cook until soft, about 2 minutes.
Add the ham bone, diced ham, broth, Worcestershire, celery, carrots, dried beans, bay leaf, dried thyme, optional ground cumin, salt and pepper. And add any additional optional veggies. Stir the mixture.
Close the lid, set to high pressure, and after the pressure cooker reaches full pressure, cook for 60 minutes (These are the steps we did for our Instant Pot: Press "Cancel" to stop the "Sauté" setting. Press the "Manual" button. Set the time to 60 minutes.)
After the cooking time is complete, press "Cancel" and carefully release the pressure.
Remove ham bones and any excess fatty chunks from the Instant Pot and pull off any ham meat and cut into small pieces. Add the ham back into the Instant Pot. If you want a thicker soup, mash a few of the beans in the soup. Give the soup a good stir and add additional salt and pepper, to taste.
Garnish with minced parsley (optional). Serve warm with bread.
