Okay, so I know I'm the last one to figure this out, but I just made myself some scrambled eggs for breakfast, and I'm STUFFED. I feel almost too full, and for only 210 calories. And chances are the 18g of protein in the things will keep me full till lunch. We'll see! I almost always eat carbs for breakfast, around 350 calories of Cheerios or a bagel or oatmeal, and I like them, but man I don't feel anything like this full.
Plus I finally managed to learn a good scrambled egg technique, so they were all light and fluffy: http://www.mrbreakfast.com/article.asp?articleid=17
(I used a little spray instead of the butter called for).
