When using kale, lettuce, cut fruit or cut vegetables, wash or rinse them, and while still damp, spray them with a spray vegetable oil, like Pam, etc. before placing them on your serving tray/plate. The oil will not only make them more vibrant in color (greens adn purples are brighter, especially with kale), they will also stay fresh for the entire day or serving time. The oil will help give them a shiny, fresh look and will seal in the moisture to keep them from wilting. If any one would take them off the tray to eat, it is not harmful or distasteful.
