Place all ingredients in a blender. Blend on low for about 20 seconds, until spinach is completely chopped and all ingredients are mixed.
Put about a cup of water in the bottom of your <a href="https://amzn.to/2Uob3YU" target="_blank" rel="noopener">Instant Pot</a>; add the metal trivet. Place a <a href="https://amzn.to/2WRYQbN" target="_blank" rel="noopener">silicone egg mold</a> (sprayed with cooking spray) on top of the trivet and evenly fill each cup with the egg mixture.
Lock the lid on your Instant Pot. Set cooker for steam mode, 10 minutes. Once cook cycle is over, allow pressure to naturally release for an additional 10 minutes before manually releasing remaining pressure.
Flip silicone tray onto a plate to release egg bites. Serve immediately or store in the fridge; bites can be rewarmed in the microwave in about a minute.
