To make a fluffy-cakey omelet, microwave the beaten eggs with a teaspoon or two of waffle mix and microwave on high for about 2 minutes.
Flavor once you get the hang of it in all sorts of ways. (fruit, meat, veggies)
With no flour it will just be fluffy.
The more flour or cocoa /chocolate the more a pinch of baking powder helps.
Its an omelet of a different color.
