Radishes: Separate the radishes from their greens and store each in a plastic bag in the fridge. Use the greens within 1-2 days of purchase. The radishes will keep for a few days longer.
Red Bell Pepper: Refrigerate, unwashed, in plastic bag for use within 5 days. You may wish to blot out any moisture on the surface of the pepper with a paper towel before refrigeration, as moisture can promote decay.
Rainbow Chard: Store unwashed chard, wrapped in a plastic bag, in the refrigerator for up to three days. Wash well before use to remove any dirt or sand. Chard can be eaten cooked or raw. When cooking the stems, add to the pan a little before the leaves, as the stems require more cooking time.
