I drive now but when I bike I bring the same general stuff: a chicken cutlet or meatless fungi cutlet (not as bad as it sounds) cut in half & put ea half in a sep. ziplock bag w a small lettuce wedge. this way I can space out when I eat the halves, instead of all at once. another baggie of baby carrots & yet another baggie with a larger lettuce wedge. box of yogurt covered raisins & a granola bar. the bags are reusable. everybody's food is different. mine is pretty sparse cuz I drive to work & sit in a chair all day (except for a 20 min gym workout at lunchtime. usually eat half on my way to the gym & the other half when I run out for coffee in the afternoon) (the granola bar goes with my coffee when I get back to the office from the coffee run. the raisins, larger lettuce wedge & carrots are for the drive home)
