Take mayonnaise and mustard in individual packets to spread on hard rolls, tortillas or bread. Round out your picnic menu with fresh or dried fruit, raw vegetables, chips and cookies for dessert. Once you're through eating, put leftovers back in the ice chest right away. Make sure there's enough ice left in the chest to keep leftovers that need refrigeration cold and safe until you can get them home and into the refrigerator again. If not, it's wiser not to save perishable items.
