What better way to celebrate the Easter season than to watch a fast food chain combine two tasty* snack items to create the Frankenstein’s monster of sandwich offerings?

In the UK, Subway and Cadbury are doing just that. For one day only (Good Friday), anyone brave enough to eat this can get a Subway UK’s new Cadbury Creme Egg Easter SubMelt at no charge (not counting any uncovered medical care needed afterward.)

No, this sandwich doesn’t feature tuna, tomatoes or provolone; it’s nothing but melted Creme Eggs on Subway’s toasted Italian bread. And there’s a catch to the promotion, obviously, and it’s not just that the sandwich looks absolutely revolting (see the photograph above.) Only 500 sandwiches will be made, total, for the duration of the promotion.

If you’re keen to try one, catch a flight overseas and get yourself to one of the select Subway locations in England: at Tottenham Court Road, central London and Central Shopping Centre, Liverpool this Friday.

“Our Italian White Bread and Cadbury Creme Eggs make the most flavorsome combination, a perfect seasonal treat,” Rusty Warren, Subway’s senior manager of new product development and innovation, was paid to say.

Over at Cadbury, puns were deployed to defend the decision to sell this culinary equivalent of The Thing With Two Heads. Charlotte Docker, brand executive for Cadbury Creme Egg, said, “When Subway approached us to create this eggs-traordinary Submelt, we simply couldn’t resist.” 

“The highly-anticipated Creme Egg season is in full swing and we’re so excited to launch this innovative product with Subway as a final hoorah of the season,” she continued.

While there are no plans to serve this in the United States this year (or any year), it wouldn’t hurt to write your local legislators now to get some kind of protections in place.
