First, take your bag of split peas and rinse them with cold water. Take a look and make sure there are not any small stones in the package.
While the peas are draining I would suggest chopping all of your vegetables before you do anything else. Cut onion, carrots, and celery into uniform bite-size. I use my Vidalia Vegetable Chopper to make all the vegetables a uniform size and it goes more quickly.
Add to a 6-quart Instant Pot the package of split peas with the package of flavor seasoning, the chopped onion, carrots, celery, garlic, the chopped ham, wine vinegar, 4 cups of vegetable broth, and 4 cups of water.
Stir and set the lid on top and close the vent.
Set the Instant Pot to High Pressure for 10 minutes with a 10-minute natural release.
Serve with warm crusty bread.
