The burritos come filled with spicy rice, beans, salsa, lettuce, and chipotle mayo and can come filled with either Original Recipe, Zinger, or Pulled Chicken.
The fried chicken chain also regularly offers various wraps in the UK, including the Twister that has been long-discontinued here in the US.
It should be noted that there are around 800 KFC restaurants in the UK and only 4 Taco Bells.
