Begin by laying a kale leaf flat and placing one peeled hardboiled egg in the center. Gently fold the kale around the egg to cover it completely.
Take one slice of prosciutto and tightly wrap it around the kale-covered egg, using the prosciutto to hold the kale leaf in place.
Repeat this process for the remaining three eggs.
Lightly sprinkle the wrapped eggs with salt and freshly ground black pepper for a final layer of seasoning.
Pour the water into the inner pot of your Instant Pot and place the metal trivet or a steamer basket inside. Carefully arrange the four wrapped eggs on the trivet.
Secure the Instant Pot lid, ensuring the steam release valve is set to the 'Sealing' position. Select the 'Manual' or 'Pressure Cook' function and set the timer to 5 minutes at High Pressure.
Once the cooking time is complete, perform a quick pressure release by carefully turning the steam release valve to the 'Venting' position.
After the float valve has dropped, cautiously open the lid. Use tongs to transfer the warm prosciutto-wrapped eggs to a plate and serve immediately.
