Place six large eggs on the trivet or steamer basket inside your cooker.
Add a cup of water into the bottom of the cooker. Lock the lid with the sealing ring in place and set to manual high pressure for 5 minutes.
Quick release the pressure carefully. Once fully released, open the lid carefully.
Transfer eggs to an ice water bath to cool quickly.
Scoop out yolks into a bowl and mash with a fork.
Add Caesar dressing, half of the Parmesan and half the shredded lettuce to mashed yolks and stir well. Pipe mixture back into egg whites. Sprinkle with remaining cheese, lettuce, and crack some black pepper over all.
