Add olive oil to the Instant Pot and select the Sauté function. Set to high and once the display reads “hot,” add your chicken breast meat. Season the chicken on both sides with the garlic powder, plus salt and black pepper, to taste.
Sear chicken breasts on each side until golden brown, approximately 4-5 minutes per side. Remove from Instant Pot® and set aside. Add chicken broth and deglaze the bottom of the pot by gently scraping with a rubber spatula.
Add the metal trivet that comes with the Instant Pot® and place the chicken breasts on top. Add the lid and set the pressure valve to “sealing.” Select the “Manual” cooking option on the high setting and set the cooking time to 8 minutes. When done cooking, allow the pressure to release naturally for 10 minutes, and then do a quick release for any remaining pressure.
While the chicken is cooking, prepare the dressing by combining all ingredients in a container with a tight-fitting lid. Cover tightly and shake until well combined. Taste and adjust seasonings, as desired. Set aside.
Remove chicken from Instant Pot® and let rest for a few minutes, then shred with two forks. Reserve cooking liquid from the pot to use in other recipes or freeze for later use.
Arrange mixed salad greens on a platter and top with the shredded chicken, strawberry, Feta cheese, and crunchy pecans. Drizzle the balsamic dressing on top and serve immediately. Enjoy!
