Taco Bell (NYSE: YUM ) is making waves by bringing back a side item that many love.

Fans of the fast food burrito chain will be happy to hear that its Diablo Sauce will be back permanently. The move comes right on Cinco de Mayo–May 5th.

The sauce contains more spicy ingredients to burn your tongue and the insides of your mouth. However, if you have a mouth capable of handling that level of heat, then the sauce is perfect for you as it does have a classic Mexican salsa taste.

Taco Bell recently made a pledge to support antibiotic-free chicken only by next year.

YUM stock is up 0.2% Thursday.
