The chain famous for Quesaritos and Doritos Los Tacos is encouraging customers to pre-order a mystery new menu item. While the new product will be unveiled in a 30-second Super Bowl spot this Sunday, fans who pre-order will will be able to pick up the mystery item on Saturday afternoon.

Customers are limited to pre-ordering five of the $2.99 items each, which they can pick up between 2pm and 4pm on Saturday.

“With respect to our fans and ____-lovers everywhere, we knew they wouldn’t want to wait to get their hands on____,” Marisa Thalberg, Chief Marketing Officer for Taco Bell Corp, said in a press release that bore an eerie resemblance to Hillary Clinton’s redacted e-mail releases. “There’s just one thing: it’s a ‘blind’ pre-order… requiring just a small act of faith (not knowing what it is until you pick it up) to be at the very forefront of this impending phenomenon.”

Those not willing to take the leap of faith will have to wait to try the new menu item on Monday, Feb. 8.

One thing we do know about the item: It contains dairy, wheat and soy.
