Birds of Prey actor Bruno Oliver -- who plays the short order cook Sal in the Margot Robbie-starred DC Extended Universe film -- decided to teach fans how to make Harley Quinn's beloved egg sandwich at home.

Since the film's release, several fans have attempted to recreate the egg sandwich both Harley and the film itself hold in incredibly high regard. In a video shared by Variety, Oliver walks viewers through the exact recipe he used to craft the pivotal piece of breakfast food. He lists the ingredients as bacon, eggs American cheese and bread. He recommends using ciabatta bread in particular, as it has "nooks and crannies for the gooey eggness to go into."

Oliver admits than when he first landed the role as Sal, he was unaware of how important the egg sandwich he was asked to make would end up being to the story. "You couldn't tell from the audition necessarily and as actors, we always worry about our scenes being cut," he told Variety. "I really didn't understand the place the egg sandwich had in the movie until I saw it."

Oliver practiced making the sandwich the day before he was scheduled to film his scene for the film, describing the experience as "definitely one of the oddest preparations as an actor I've done. I spent the night destroying my kitchen making egg sandwiches over and over and over again." He also explains that while he was the one who made the sandwich on camera, it was Birds of Prey's catering chef who filmed the close-up "food porn" shots. "There are little things I can't do -- like crack two eggs with one hand," Oliver confessed.

The actor admits he was also surprised by how many moviegoers connected with the sandwich, which a hungover Harley attempts to eat as a hangover cure the morning after destroying the ACE Chemicals building (and cementing her breakup with the Joker), only to have it knocked to the ground during a chase sequence. "I've read a lot about the sandwich as a metaphor for Harley’s recovery," said Oliver. "I've read a lot that refer to Sal as the only male in the movie who doesn’t screw her over."

Directed by Cathy Yan and written by Christina Hodson, Birds of Prey (and the Fantabulous Emancipation of One Harley Quinn) stars Margot Robbie, Mary Elizabeth Winstead, Jurnee Smollett-Bell, Rosie Perez, Chris Messina, Ella Jay Basco and Ewan McGregor. The film is out on digital HD now.
