<human>:  How do I preserve fresh vegetables in the freezer?
<bot>: To successfully preserve fresh vegetables in the freezer, start by washing the vegetables thoroughly with cold water to remove any dirt or bacteria. Next, blanch the vegetables for 2-3 minutes in boiling water to help maintain their color and texture. After blanching, immediately cool the vegetables in an ice bath. Finally, pat the vegetables dry with a clean towel and place them in an airtight freezer-safe container. Make sure to leave at least 1/2 inch of headspace to allow for expansion. Label the container with the date before freezing.
