I'm insomniac, so always eat things at very unusual times: could be having a sunday roast at what everyone else would call breakfast time, for example, or a sandwich at regular-clock dinner time.
I do snack a lot, when I have money, and what I eat varies wildly - today I've had a couple of "school bars" (densely packed strawberry... thing), a few packets of "cup a soup" and some ice lollies (I don't do well in this weather). No actual non-snack food as of yet today, though.
