Today is National Avocado Day. Tell me, class, what is the most popular avocado dish … aside from avocado toast? Yes, it’s guacamole. And if you like guacamole and you also like the food served by Chipotle Mexican Grill, you can get the former free by ordering some of the latter when you order online.

You’ll need the chain’s app, which if you don’t have it can be downloaded from their website. Just select a burrito, a bowl, a salad, or an order of tacos, and then select guac either as an add-on, a side, or as an order of chips and guacamole. To avail yourself of the freebie, enter the coupon code “AVOCADO” when checking out.

Be advised, the offer is not good when ordering at Chipotle locations.
