Here is an easy breakfast idea if you don't have much time in the morning to cook. We enjoy them!!
I make mine to have an average of 2 egg whites per muffin. After I pour the egg mixture into the pans I add my toppings. Such as, peppers, spinach, cooked meat... Anything you like.
I couldn't remember the temperature and time so I set it at 350• and checked it every 5 minutes. It'll depend on how thick they are and what you put in them. Then in the mornings I heat them up in the microwave and have them with my oatmeal. Let me know how you like them!
