Shake Shack has finally added avocado to its menu.

You can have it in one of two new avocado and bacon dishes, or, for the first time, add it to any other burger or sandwich on the menu.

Shake Shack launched its Avocado Bacon Menu Wednesday. You can order either a burger or a sandwich with freshly-sliced avocado and Niman Ranch applewood-smoked bacon.

The burger comes a Shake Shack patty, while the sandwich adds a crispy chicken breast, lettuce, pickles, and buttermilk herb mayo to the avocado-bacon combo.

Prices depend on where you are, but at the Flatbush restaurant in Brooklyn, New York, the burger costs $7.89 for a single and $10.69 for a double, while the sandwich costs $8.79. Adding avocado slices to other menu items costs $1.25.

The two new dishes are available until June 30 at all US locations, but Shake Shack told Thrillist that the avocado add-on option was here to stay, and that avocado was one of the chain’s most requested additions.

Avocado has boomed in popularity in recent years, causing prices to soar, and it has become an embodiment of millennial culture thanks to memes about avocado toast. The food industry has tried to find creative ways to serve avocado beyond toppings and as guacamole, and some restaurants even base their entire menu on the green fruit.
