Omelet in a Coffee Cup

This is one of our favorite hearty breakfast choices.  The 7-year-olds can make it themselves.
Get a microwavable coffee cup.  Spray the inside with cooking spray or spread some butter on the inside to allow for easier release and cleaning.  Crack one or two eggs into the cup.  Add about 1 tablespoon of milk.  Add some shredded cheese, pieces of deli meat, salt, pepper, or whatever else.  Microwave on high for 60-90 seconds.  If it is still quite runny, cook an additional 30 seconds.  Repeat if needed.  You can eat it out of the cup and save dirtying a plate.  But if you do plate it, it comes out in a fun shape.
