I don't discriminate much between different types of food...I'll eat the same types of food for breakfast, lunch, dinner, whatever.
Right now, what seems to be working well for me is eating 5-6 times/day.  I usually eat lunch and an afternoon meal, and sometimes the last meal, at work.  Three things are key in keeping me on track for at work eating:  portion control, ease, and easy calorie counting for my food log.
These days, it is a lot of:
Eating Right frozen meals (I keep several in the work freezer)
Packets of oatmeal with some slivered almonds tossed in
Lowfat yogurt with slivered almonds and fibre one cereal
Microwave-ready soups
Ready-to-eat, no-draining-needed tuna fish tubs (expensive, tho)
I wait and eat the stuff that takes more prep at home (vegetables and stuff)
