PepsiCo has extended its relationship with US restaurant chain Taco Bell with the launch of tortilla chips.

Taco Bell already sells a Doritos-branded taco in its restaurants and the companies are taking their relationship into US retail stores.

They have developed two tortilla chip products sold under the Doritos Locos Tacos, or DLT, brand. Both lines – a Nacho Cheese DLT and a Cool Ranch DLT – include two chip varieties in one bag: Doritos chips and chips “reminiscent” of tacos on sale at Taco Bell restaurants, PepsiCo said.

“It is a simple, yet brilliant, concept that unites two fan favourites – Doritos chips and the Taco Bell Crunchy Taco for a truly one-of-kind snacking experience,” Ram Krishnan, vice president of marketing at PepsiCo’s Frito-Lay business, said.

The chips are available nationwide for “a limited time” in three sizes: an 11-oz. bag for a suggested retail price of $4.29; a 3.4-oz. bag for $1.49; and a 2.1-oz. bag for 1.09.
