Re: Lunch and breakfast ideas....
I often have Greek yogurt (plain) with a bit of granola or European style muesli, raisins, chopped dates, and a touch of honey. It keeps me full. I'll add fresh fruit if it's not hideously expensive.
Oatmeal/porridge with fresh cut bananas and raisins when I need something hot.
