Let's get started in cooking our split pea soup! Turn your Instant Pot on and press the sauté setting. The time will show 20 minutes on the display, but you only need to sauté for about 5 minutes or so.
Drizzle a couple of tablespoons of olive oil, add (diced onion, optional) carrots and sauté for about 2 to 3 minutes stirring occasionally. Then add shredded leftover large chicken breast and sauté for another minute or so.
After the steam is released, open the lid, turn the instant pot off, and add dill and parsley. Close the instant pot lid again and let the fresh ingredients steam through for about 5 minutes or so while the instant pot is still off.
