Packing up lunch items into reusable containers eliminates the single use plastic sandwich bags and allows you to dispense the amount that will be eaten in a meal, cutting down wasting uneaten food. Buy larger quantities of snacks, carrots, applesauce, yogurt, or cheese, and just pack the quantity needed for one meal, saving you money compared to the pre-packaged single servings, which also produce a lot more trash. Dips, ketchup, sauces, and dressing can also be portioned into small reusable containers. Cloth napkins and stainless steel or bamboo utensils are great options for replacing the disposable ones. Pour water or other drinks into a reusable bottle, or use a thermos to keep drinks hot or cold for hours. Then pack everything in a reusable lunch box or bag! Bento box style lunch boxes offer a variety of options for container types and sizes.
