Just a tip since we all love to eat our 4 cups of veggies a day and to help save money on produce.
Buy those reusable Produce Bags, here in Canada one product is called PC Green. They work great, my romaine, iceberg lettuce, cucumbers, broccoli, cauliflower and celery last for at least a couple of weeks without spoiling.
They're a good fair size for large heads of romaine, reusable up to 12 washes too.
It's a good thing
