It’s a simple trick: if you whisk egg whites until they are fluffy, they expand, by a huge amount. Add a few tasty low fat ingredients and you can create a big breakfast that is healthy, filling, and very low calorie.
I can’t say this is fast and easy. It’s a long slow Sunday afternoon recipe, and it creates quite a bit of washing up! But there’s a good return on investment – for an hour or so of Sunday afternoon baking, you can have several very healthy dinners and lunches made ready for the week.
