Grab the guacamole - it's National Taco Day!

Break out the salsa and guacamole! Sunday is National Taco Day.

Hard shell or soft, chicken, beef, fish or veggie, tacos are loved and eaten by millions each day.

Last year, the U.S. consumed 4.5 billion tacos, according to the National Taco Day website.

That equals to about 490,000 miles of tacos - enough to take to you to the moon and back.
