Processed meat on burger ?

Been supporting Nando's for years. Their chicken burgers were the best, until now..... Went to have a Nando's burger yesterday, and it tasted "raw" and the texture of the meat was not normal. On close inspection of the meat, I was shocked to see that it is now a piece of processed meat, instead of the usual chicken "fillet" that they used to have. How aweful ! I managed to eat half the burger, couldn't stomach the rest. Goodbye Nando's, that's the last time you'll see me, and I will let others know about this too !
