Robert McMullin doesn’t believe in pineapple as a pizza topping. You won’t even find it as an option on the menu at his restaurant, Piatto Neapolitan Pizzeria in Wichita, Kansas. Well, except for today.

In honor of National Pizza Party Day, traditionally observed on the third Friday of May, McMullin is giving in to pineapple partisans with a one-day special: the Pineapple Al Pastor pizza.It’s such a rare occasion that McMullin has even created a Facebook event for it. “It’s your one and ONLY night to get pineapple on pizza,” the post states. “So you better get in here.”

The pizza features pineapple and al pastor meat (seasoned and marinated pork) supplied by Taqueria La Chona, a popular Mexican restaurant in Wichita.

Piatto has also partnered with nearby Hopping Gnome Brewing Company to promote the pie. Hopping Gnome is celebrating its eighth anniversary with the grand opening of a new location on Friday, May 19. Customers will be able to scan a QR code in the brewery’s tap room to order the Pineapple Al Pastor pizza, then stroll across the alley to pick it up at Piatto.

Other pies on the Piatto menu include the Margherita With Speck (smoked prosciutto, fresh basil, fresh mozzarella and olive oil), the ‘Nduja (‘nduja, basil, fresh mozz and olive oil) and the Diavola (spicy salami, shaved garlic, smoked sea salt, fresh mozz and olive oil). The pies are baked in a massive Stefano Ferrara oven at 850°F to 900°F for 60 to 90 seconds. To learn the Neapolitan pizza craft, McMullin studied under master pizzaiolo Enzo Coccia in Naples, Italy.

But pineapple fans have to get the Pineapple Al Pastor while it’s hot. It won’t be back for another 365 days, McMullin told the Wichita Eagle. “I mean, I like pineapple on this pizza, but pineapple is never going to be on our menu,” he said. “It’s not going to happen.”
