If using the Instant Pot, you can use FROZEN chicken breasts. Add 1/2 Cup of Chicken broth to the above ingredients. Set to High Pressure for 18 minutes, and manually release the pressure.
Catalina Dressing
Add all ingredients except olive oil into a blender. Mix on high, slowly pouring in the olive oil for 1 minute.
Mashed Potatoes
Wash, chop and boil for approximately 15 minutes or until potatoes are very soft.
Drain potatoes and return to pot. Add butter and Greek yogurt and mash the potatoes. I like to use an electric mixer.
Notes
I use the 6-quart Instant Pot for all of my recipes. See details in the "Featured Products" section.
