The home of the Big Mac is going Big Guac.

McDonald’s has added guacamole to the menu, and many customers are lovin’ it.

McDonald’s new Pico Guacamole mashes together Hass avocados with Roma tomatoes, onion, jalapenos, serrano peppers, salt, garlic and cilantro. It will be spread on a handful of its Signature Crafted Recipes sandwiches, including the Artisan Grilled Chicken and the Buttermilk Crispy Chicken, at no extra cost on the $4.99 and up sammies.

The Golden Arches is the latest mainstream restaurant chain giving our avocado toast-obsessed population something to guac about. Starbucks began hawking pre-packaged organic avocado spread this spring, which customers can spread on a bagel for just less than $4 a sammie. Customers have flocked to Chipotle for guacamole, and Chick-Fil-A features an avocado lime ranch dressing. Burger King rolled out a California Whopper with avocado spread and Swiss cheese a few years ago, but it’s no longer on the menu. And Brooklyn has even opened an avocado-only restaurant called the Avocaderia.

See: Holy guacamole! Rising avocado costs

But Americans are gobbling so many avocados now that prices for the fruit have hit at an all-time high. Just before Cinco de Mayo, the average price for an individual avocado jumped to $1.25 a pop – and up to $1.50 for organic avocados, or between $1 and $2 more than last year. Chipotle was forced to raise the price of its guac by about 5% in one-fifth of its stores earlier this year, and Subway had to yank the trendy ingredient off the menu.
