You can keep lettuce in the produce bin, then us your spinner to wash it, then find a new container for it, OR you can just wash your lettuce in the salad spinner, and let it live there.
Downside – if you wash lots of items in your spinner this plan won’t help you.
Upsides – only one container, you’re more likely to eat a salad if the darn lettuce is washed and ready, and it actually will keep your lettuce fresh for about a week (I’ve done it).
