Niki Lowry of The Daily Muse has a great idea for bringing a salad lunch to work — bring it in a Mason jar! On top of looking beautiful and inspiring everyone that opens the office fridge to want salad too, the vertical orientation serves a purpose. By layering from heaviest (dressing) to lightest (lettuce), with things like beans and tomatoes creating a dressing/lettuce partition, you keep the lettuce from getting drenched and wilted before you crack it open for lunch.
