How to keep cut vegetables and lettuce crisp for days

Need to keep your chopped bell peppers fresh a few days more? Try this hack: Use a sharp knife to cut your peppers. A dull knife could damage the exterior of the veggie. Remove the stem and seeds. Then cut into slices or chunks. Lay your pepper slices on a paper towel and wrap the towel around the peppers.
