I eat breakfast at home and usually carry my lunch in my seatbag, a Carradice Barley, Pendle or Acorn. I also keep a stash of food in my office (granola bars, instant oatmeal, soup) that I replenish on days that I drive. Sometimes I have leftovers for lunch, other times a sandwich. I also usually bring a banana, apple and a snack like Wheat Thins or pretzels.
