tomatoes, cut (if available)
dressing (Italian, balsamic vinegar, raspberry vinegarette, etc)
Put lettuce/spinach on bottom of plate. Add the remaining ingredients (and more if you like. Carrots, strawberries, blueberries, and onions are great additions as well!) with dressing either right before you eat or leave the house for work. Enjoy with triscuits, pita chips, or fresh bread.
