Add peas, chicken stock or water, and bay leaves. Stir to combine, then cover pot and bring to high pressure. Cook for 20 minutes, then rapidly release pressure by opening the air valve. Open pot lid, stir contents until smooth, season to taste with salt and pepper, and serve. Carefully clean the pressure cooker's gasket and valves as soon as the pot is cool enough to handle; pea soup can easily clog valves, which can cause your cooker to over-pressurize the next time you use it. Soup can be stored in the refrigerator for up to 1 week.
