Water is the enemy. If you only use a small amount and the bag is open for days, try laying the contents of the bag unto paper toweling, Roll the towel jelly roll style. Store this roll in a plastic bag with holes in it on the fridge shelf. This will keep the leaves dryer and longer. Refresh the lettuce leaves in cold ice water to bring them back to crispness.
