Spring greens doesn't last long, so buy only what you plan to use within a few days. To clean, fill a bowl with cold water, and add greens, swishing gently. Scoop out greens. Drain water off. Repeat with fresh water until no grit remains at the bottom of the bowl. Dry with a salad spinner, or pat with paper towels. Store washed greens in a resealable plastic bag lined with dry paper towels in the refrigerator up to 1 day.
