Sainsburys spicy hell's chicken

First, I was surprised to see this black bun filled with spicy chicken at Sainsburys as they don't usually have things like this.
Secondly, it was so delicious like restaurant/cafe quality.
It wasn't spicy but the onions made it really tasty along with the red Leicester cheese and creamy slaw that was not too sweet.

I warmed it in the microwave for 30 seconds just to bring it to room temperature and it tasted amazing
Overall, really worth trying.

Made by the Greencore group so it was no surprise I liked it because I liked the previous products like the Marks and Spencers like the no salt beef bun, Boots vegan sandwiches, Sainsburys festive roast sandwich with gravy.
