In a small bowl, lightly beat eggs, feta, dill, broccoli, milk/cream, and broccoli.
Transfer mixture into a well greased springform pan (I use 7" in diameter).
Cover the pan with foil.
Add 2 cups of water to the instant pot stainless insert.
Place the trivet in the pot.
Place the springform pan on the trivet.
Seal the Instant Pot.
Set the Instant Pot to high pressure (manual or pressure cook button) for 20 minutes.
Allow the pot to naturally depressurize for 10 minutes.
Release remaining pressure.
Add cheese topping, if desired and allow to sit until melted, or place under oven broiler if desired ( I skipped the broiling).
