I'm currently 122 lbs, and if I ate what you do (unless lunch is a ribeye and baked potato smothered in sour cream), I'd be hungry all day long. Personally, if I were you, I'd increase both my protein and fat at all meals. If you are still in the "saturated fat is bad" camp, at least add things like nuts, seeds, olives, and avocado.
If I eat breakfast at 7am and I want it to hold me through until lunch, then I eat 2 eggs (fried in butter), spinach (wilted in bacon fat), and some fried potatoes (pan fried in butter). YMMV, but that works for me.
