Crack the eggs into a mixing bowl or into the Ninja Foodi Hot Cold Blender. Add the heavy cream, cream cheese, onion, salt and pepper. Select the smoothie function.
Butter or oil the egg bite mold and the silicone cover.
Add the ham and cheese cubes to the blender. Pulse 2-3 times.
Pour the egg mixture into each well about ½ way. Since the ham and cheese settles in the blender, you want to make sure each egg bite gets some of the ham and cheese. Spoon or pour out the remaining egg mixture to fill each well ¾ of the way full. You want at least ¼" at the top to allow for rising. Cover the egg bites with foil or a silicone cover.
Add 2 cups of water to the inner pot. Place the egg bites on the rack in the low position. Place the rack in the inner pot. Put the pressure lid on and turn the valve to VENT.
Select the steam function for 12 minutes. When the time is done, remove the lid. Remove the rack with the egg bites and uncover. Allow to cool just a few minutes.
Use a cake tester or a knife and make sure the egg bites are releasing from the sides. If they aren't, let them cool a little longer. If they still aren't pulling back from the silicone, then run a cake tester or butter knife around the edges.
