Advantages?……….Maybe none, but if I was asking a nutritionist for advice on ideas for breakfast and the response was try apples, bananas or carrots then I’d be thinking what a waste of time that was.
In response to the OP, toast and Eggs (poached, scrambled, boiled or fried) is pretty hard to beat for a ‘go to’. Try four instead of two. It might help address your problem there ?
