Whether you use a lunch box or brown bag it, Tuesday marks National Pack Your Own Lunch Day.

No one is quite certain how the holiday got started, but March 10 is the day each year that people are encouraged to pack a lunch and take it with you to work, school or wherever you happen to be spending the day.

To celebrate, the Boris & Robyn Show is asking listeners to share photos of their packed lunches on Tuesday morning. Either upload them to our Facebook page or post them on Twitter or Instagram using the hashtag #WPDH.

We'll collect the best and share them with the WPDH audience.
