Harkening back to the days of KFC's Double Down sandwich, Arby's has (secretly) released what it calls the Meat Mountain sandwich.

It all started unexpectedly. The restaurant chain was trying to show people that it sold far more than just roast beef. So, the Washington Post explains:

To change that [perception], the company made [a] poster showing a tall stack of every meat on the menu, from bacon to brisket.

And then something unexpected happened.

“People started coming in and asking, ‘Can I have that?’” said Christopher Fuller, the company’s vice president of brand and corporate communications. So Arby’s began granting their wish.

The Meat Mountain costs $10 and it's not listed on the regular Arby's menu. You must ask for it by name (perhaps under your breath) when you order. Your sandwich includes:

2 chicken tenders
1.5 oz. of roast turkey
1.5 oz. of ham
1 slice of Swiss cheese
1.5 oz. of corned beef
1.5 oz. brisket
1.5 oz. of Angus steak
1 slice of cheddar cheese
1.5 oz. roast beef
3 half-strips of bacon
