Not being so hungry for the rest of the evening and even into the next morning is pretty much a combination of having a meal rich in some good fats and that didn't send your blood sugar sky rocketing so you skipped over the inevitable crash. Both of those things basically keep you feeling satiated for a long time, so yeah, pretty normal.
Pretty much any day that I'm good about having a steak and salad or something for breakfast before 8am I won't be hungry again until mid-afternoon.
