Start with placing the chicken in the Instant Pot. You can use frozen or thawed chicken breasts for this.
Season with the pepper, salt, and Italian seasoning. Pour the chicken broth over the top.
On manual at high pressure, set the timer for 10-16 minutes (5-8 minutes per pound). Use the natural release method after the cook time.
Take the chicken out, and put it in a bowl. Use two forks to shred up the chicken into small pieces, or you can slice it up into chunks if you prefer. To avoid dry chicken, drizzle a little dressing over the top of the bowl and mix together to keep it nice and juicy!
Place a large amount of romaine lettuce in the bottom of each serving bowl. Then add the chicken, parmesan, croutons, and dressing. Mix together until the dressing is evenly coating everything. Then enjoy!
